摘要： Systems and methods for improved photonically-assisted RF filtering. Presently, processing of wide-band RF signals involves the use of multiple specialized equipment to isolate a region of interest from the spectrum. The present invention discloses the use of a modulation system to upconvert the RF signal onto the sideband of a light source such as a laser, an optical filter sub-system comprising a plurality of filtering units that function as combinations of HR and FTR filters, and a resonant channelizing filter for noise reduction and rejection of undesired channels, and means for control and agility of a piecewise coherent optical filter. The resulting filtered RF signal may then be downconverted to the electrical domain for further signal processing.

摘要： A high rate radio frequency (RF) link system and method for spatially multiplexing data transmission is presented. The system can comprise a common communications point characterized by a first collection of antennas having independent channels interconnected with a known latency connection to a central process location, such as with optical fiber; and a second similarly configured collective endpoint or set of endpoints wherein multi-path between the first collection and the second collection is negligible. Signal decorrelation between independent channels is achieved through a combination of spatial separation and signal processing. In one aspect, decorrelation is performed using near-maximum likelihood Multiple-Input Multiple-Output signal processing.

摘要： A system and method for transporting encrypted data having a transmitter and a receiver is provided. The transmitter generates a sequence of optical pulses, which are copied and output as identical channels. The identical channels are modulated by a plurality of modulators using data to generate a modulated data signal. Respective spectral phase encoders coupled to each of the plurality of data modulators encode respective modulated data signals using a plurality of mutually orthogonal phase codes that are individually associated with the respective spectral phase encoder. These encoded data signals are combined and code-scrambling by a spectral phase scrambler t using a scramble code as an encryption key to generate an encrypted signal. A receiver reverses the encryption to extract the data.

摘要： Apparatus and methods of simultaneous transmission and reception in a single-antenna radio transceiver. The transceiver may be used, for instance, for communication between at least two terminals, by use of multiple intermediate recruited transceiver nodes. The recruited transceiver nodes receive a signal from a master mode, and then retransmit the signal to a receiver. The recruited transceiver nodes are designed to have reduced interference between the transmit channel and the received channel. In accordance with one aspect of the present application, embodiments can achieve more robust wireless communication between a transmitter and an over-the-horizon receiver. The robust wireless communication will have improved resistance to interference, including self-interference, and improved communication range.
