摘要： Data files with digital envelops are used (1) for embedded identifiers for digital right management (DRM), and (2) as means delivering additional data or new information via repeated re-broadcasting process by many broadcasting service providers. The new DRM applications offer additional privacy and survivability while data is in storage and/or transported on cloud. Wavefront multiplexing/demultiplexing process (WF muxing/demuxing) embodying an architecture that utilizes multi-dimensional waveforms has found applications in data storage and transport on cloud. Multiple data sets are preprocessed by WF muxing before stored/transported. WF muxed data is aggregated data from multiple data sets that have been “customized processed” and disassembled into any scalable number of sets of processed data, with each set being stored on a storage site. The original data is reassembled via WF demuxing after retrieving a lesser but scalable number of WF muxed data sets. A customized set of WF muxing on multiple digital files as inputs including at least a data message file and a selected digital envelop file, is configured to guarantee at least one of the multiple outputs comprising a weighted sum of all inputs with an appearance to human natural sensors substantially identical to the appearance of the selected digital envelop in a same image, video or audio format. The output file is the file with enveloped or embedded messages. The embedded message may be reconstituted by a corresponding WF demuxing processor at destination with the known a priori information of the original digital envelope. In short, digital enveloping/de-enveloping can be implemented via WF muxing and demuxing formulations. WF muxed data featured enhanced privacy and redundancy in data transport and storage on cloud. On the other hand, data enveloping is in a different application domain from most of WF muxing applications as far as redundancy is concerned. Enveloped data is intended only for limited receivers who has access to associated digital enveloped data files with enhanced privacy for no or minimized redundancy.

摘要： Enveloping techniques using incoherent wavefront multiplexing (WF muxing or K-muxing) will enhance privacy protection on data communications. The disclosure relates to methods and architectures of packing or enveloping data using WF muxing, or K-muxing, for information transport via multiple communication links such as concurrently via multiple satellites, airborne platforms, wireless terrestrial links, and/or other wireless links. The multi-link communications may include the use of cloud transport of multiple WF-muxed data packages. It is focused to appearance of a digital envelop and reliability of enclosed data. The K-muxing on information digital streams before modulation in a transmitter shall provide enhanced data privacy and better availability. The WF multiplexed (WF muxed or K-muxed) information data streams will be individually and concurrently sent to the multiple links accordingly for data transport. The corresponding WF demuxing or K-demuxing will be performed on received K-muxed information digital stream after demodulation in a receiver. The terms of information data or digital information streams are used to differentiate them from those of data signals or digital signal streams. In a transmission, information data usually will be modulated by modulators and converted into data signals before being transmitted. Similarly in a receiver, a received digital signal stream is demodulated by a demodulator and become a digital information stream. The incoherent K-muxing and K-demuxing will be used for processing information data or digital information streams for the benefits of enhanced privacy and better availability. On the other hand, the coherent K-muxing and K-demuxing for processing data signals or digital signal streams will be used for power combining and/or dynamic resource allocations for communications channels.

摘要： Four independent technologies are incorporated in this invention to efficiently and cost effectively implement dynamic last mile connectivity. The four technologies are passive optical networks (PON), Small cell, wavefront multiplexing (or K-muxing), and digital beam forming (DBF). We have filed US patents for communications architectures featuring K-muxing overlaid over low cost of PON. Those inventions relate particularly to resource allocation in passive optical networks (PON) via wavefront multiplexing (WF-muxing or K-muxing) and wavefront demultiplexing (WF-demuxing or K-demuxing). The “WF-muxing in PON” can be configured for performing remote digital beam forming (RDBF) over a service area covered by multiple small cells. The RDBF may generate multiple shaped beams with enhanced connectivity and better isolations over a same frequency slot concurrently to serve multiple users over the coverage area.

摘要： Presented is a multi-channel data process to utilize wavefront multiplexing for data storage and data stream transport with redundancy on cloud or in a distribution network. This processing features additional applications for multi-media recording and data communications via transponding platforms including satellites, unmanned air vehicles (UAVs), or others for better survivability and faster accessing. Multiple concurrent data streams are pre-processed by a wavefront multiplexer into multiple sub-channels or wavefront components, where signals from respective data streams are replicated into sub-channels. These replicated data streams are linked via a unique complex weighting vector (amplitude and phase or their equivalents), or “wave-front”, which are also linked by various spatially independent wavefronts. Additionally, probing data streams are embedded and linked via some of the independent wavefronts. Aggregated data streams in sub-channels are unique linear combinations of all input data streams. Generating redundancy for stored or transported data are options in the WF muxing process. Post-processing via a wavefront de-multiplexer converts various sub-channel data streams back to the original data streams, utilizing the embedded known priori data streams as additional knowledge for reducing degrees of freedom to restore orthogonality or independency among multiple wavefronts.

摘要： Security on data storage and transport are important concerns on cloud computing. Wavefront multiplexing/demultiplexing process (WF muxing/demuxing) embodying an architecture that utilizes multi-dimensional waveforms has found applications in data storage and transport on cloud. Multiple data sets are preprocessed by WF muxing before stored/transported. WF muxed data is aggregated data from multiple data sets that have been “customized processed” and disassembled into any scalable number of sets of processed data, with each set being stored on a storage site. The original data is reassembled via WF demuxing after retrieving a lesser but scalable number of WF muxed data sets. In short, the WF muxed data storage solution enhances data security and data redundancy by, respectively, creating a new dimension to existing security/privacy methods and significantly reducing the storage space needed for data redundancy. In addition, WF muxing/demuxing methods enable a monitoring capability on the integrity of stored data.

摘要： Presented are methods that utilize wavefront multiplexing for enabling linearly-polarized terminals to access circularly-polarized satellite transponders. The methods disclosed herein feature (1) polarization formation capability that renders transmitted signal conditioned on circularly-polarized channels through multiple linearly-polarized feeds, and (2) polarization-conversion capability that compensate path differentials introduced by electromagnetic wave propagation channels. Data streams to be transmitted are pre-processed by a wavefront multiplexer into multiple wavefront components in linear polarization formats, where signals from respective data streams are replicated into linearly-polarized sub-channels. These replicated data streams are linked via a unique complex weighting vector (amplitude and phase or their equivalents), or “wavefront”, which are also linked by various spatially independent wavefronts. Additionally, a probing signal is sent on the transmitting side and linked via some of the independent wavefronts. Aggregated signals in linearly-polarized sub-channels are unique linear combinations of all input data streams. Aggregated signals in turn appear in circularly-polarized formats and propagate through circularly-polarized channels including circularly-polarized satellite transponders and a circularly-polarized teleport on the receiving side. Correlation between the circularly-polarized signal and the probing signal is sent back to the transmitting side that drives the polarization-conversion function toward the optimal state such that this correlation is lower than a pre-defined level. Accordingly, an optimally configured satellite communication system either (1) enables the linearly-polarized terminal on the transmitting side to access right-hand circularly-polarized satellite transponder without interfering the left-hand circularly-polarized satellite transponder, or (2) enables the linearly-polarized terminal on the transmitting side to access left-hand circularly-polarized satellite transponder without interfering the right-hand circularly-polarized satellite transponder.

摘要： This invention takes advantages of common coverage areas of two groups of concurrent shaped fan beams in a field-of-view by both clusters of multiple flying UAVs to function as two linear arras on sky as parts of embodiments of this invention. It shows two information data sets of transmitted signals to two groups of users independently are preprocessed by a wavefront multiplexing (WF muxing) transformation before uploaded to the linear arrays on sky. Only users in the common coverage areas can access to both WF Muxed data streams delivered by the two independent arrays in sky and thus are capable to reconstitute the two information data sets. Examples with a shaped fan beam by a first platform (Fa) with 4 flying UAVs to form a fan beam over a ground coverage elongated in a NS direction. The linear array in the first platform delivers a first aggregated information associated with K1(t)=A(t)+S(t) from a ground control facility. K1(t)=A(t)+S(t) is a first WF-Muxed data set as a first outputs of a preprocessor or WF muxing transformation from two inputs A(t) and S(t). The WF muxing features a 2-to-2 Hadamard transformation. Similarly K2(t)=A(t)−S(t), a second WF-Muxed data set as a second outputs of the preprocessor or WF muxing transformation from two inputs A(t) and S(t), will be deliver to users in the common coverage areas another shaped fan beam elongated in a EW direction over a ground coverage by a second platform (Fb) with another set of 4 flying UAVs. Only users in the common coverage areas can access both K1(t) and K2(t), and recover A(t) and S(t). Furthermore, A(t) and S(t) may be related as two segmented substreams of an original information data set AS(t). This multipath transport concept can be expanded to N arrays in sky (where N>2) with N WF-Muxed data streams generated from M information data sets, where N≧M. As a result, the users in the common coverage areas may only need to receive M of the N WF-Muxed data streams to reconstitute the original M information data sets.

摘要： Embodiments of a communications system with multiple active scattering devices to service multiple users either indoor or outdoor over same spectrum in a communication network and a method for the system are generally described herein. Signals streams for transmission to users in spoke-and-hub configurations will utilize multiple active scattering devices. Three categories of operational concepts are presented: (1) multiple scattering devices arranged geometrically bundled together to function as active mirrors or retro-directive repeaters, (2) distributed man-made scattering devices placed to enhance channel bandwidth in between a hub and a common service area via frequency re-use, and (3) organizing distributed active scattering devices by remote beamforming for servicing a small common coverage area indoor or outdoor with enhanced bandwidth. All three techniques are for service with enhanced bandwidth and angular resolutions via frequency reuse, and extended service range via coherent operations of scattering devices.
