摘要： Radiotelephone communications, such as voice or data, are processed to produce a pilot symbol assisted modulation (PSAM) communications symbol sequence, the PSAM communications symbol sequence including a plurality of predetermined pilot symbols interleaved with a plurality of information symbols representing the radiotelephone communications. The PSAM communications symbol sequence is communicated over a radiotelephone communications channel having a transfer characteristic, producing a sequence of communications symbol data representing the communicated sequence of communication symbols. Pilot symbol data, corresponding to pilot symbols, and information symbol data, corresponding to information symbols, are identified in the sequence of communications symbol data. A data-augmented estimate of the transfer characteristic of the radiotelephone communications channel is generated from the pilot symbol data and the information symbol data. Estimates of information symbols are generated from the corresponding information symbol data and the generated estimate of the transfer characteristic. Radiotelephone communications are decoded from the generated estimates of the information symbols. Preferably, estimates of the transfer characteristic are iteratively generated by identifying a group of information symbol data corresponding to a group of information symbols, generating estimates of the group of identified information symbols from the group of information symbol data and a previously generated estimate of the radiotelephone communications channel transfer characteristic, and generating a new estimate of the transfer characteristic from the pilot symbol data, the information symbol data, and previously generated estimates of information symbols.

摘要： In a time division multiple access (TDMA) radiotelephone communications system, a spread spectrum random access channel signal representing a random access message is communicated from a radiotelephone to a central station according to a spreading sequence. In response, a TDMA radiotelephone communications channel is assigned to the radiotelephone. A time division multiplexed radiotelephone communications signal is communicated between the radiotelephone and the central station on the assigned TDMA radiotelephone communications channel over a time division multiplexed carrier frequency band. Preferably, in communicating the spread spectrum random access channel signal, a random access channel signal, representing the random access channel message, is direct sequence modulated according to the spreading sequence to produce a direct sequence modulated random access channel signal. According to a two-stage detection aspect, a synchronization sequence may be associated with a plurality of spreading sequences. The synchronization sequence may be first detected from the communicated spread spectrum random access channel signal, and in response to detection of the synchronization sequence, one of the plurality of spreading sequences associated with the detected synchronization sequence may be detected. A station identification may be assigned to the radiotelephone, with the station identification preferably represented by a digital station identification word. The synchronization sequence and the spreading sequence may be identified from the station identification word, thus associating the synchronization and spreading sequences. The spreading sequence may also be randomly generated from the station identification word.

摘要： Systems and methods are provided that disclose a network service for modularly constructing a software defined radio (“SDR”). A server system provides an SDR kernel (i.e., a potentially platform-neutral definition of digital signal processing functionality and control operations necessary to implement the core portion of a software defined radio implementing a particular radio standard) to a client system. The client system may select a desired SDR kernel through a variety of means disclosed herein. While some SDR kernels may be provided for free and unrestricted use, others may be purchased or subscribed to and additionally restricted by digital rights management (“DRM”) policies. Based upon the agreed upon payment terms and any other restrictions, a customized set of DRM policies may be applied by the server system to the SDR kernel before sending it to a client system. Additionally, the server system may provide a description of governmental regulations applicable to a given locality.

摘要： A wireless technology (e.g., Wi-Fi) coexistence architecture and method are disclosed for managing potential conflicts between wireless technology interference sources. A coexistence driver maintains a conflict map identifying potentially conflicting wireless technologies on a computing device. Such technologies, due to their use of overlapping transmission frequency spectra, potentially create signal interference with one another while transmitting. Managing such conflict is carried out by initially identifying conflicts arising from wireless technology interference sources based on entries within the conflict map for a set of currently installed wireless technology interfaces. Thereafter the coexistence driver creates a virtual coexistence driver to manage an identified set of conflicting wireless technology interference sources, wherein the coexistence driver regulates transmission of data sets by wireless technology interfaces according to a coexistence scheme including priority-based data transmissions.

摘要： A wireless device that desires to be connected to a wireless network broadcasts itself and its capabilities to a network using an information element. The information element is provided with frames, such as management frames, in a channel that is not protected or encrypted. The information element is forwarded to one or more potential registrar devices. One of the registrar devices then provides configuration information to the enrollee, for example as a registrar information element. The configuration information may be passed out of band or in band, and may be passed using cryptography, which may involve public key cryptography, encryption with a PIN, or some other type of secure exchange.

摘要： A protocol and method for establishing wireless data sessions between wireless clients, each of which support multiple wireless protocols is presented. A commonly supported wireless protocol is utilized to share the wireless protocols supported by the clients' circuitry. A wireless data session is then established based on the common capabilities of the wireless clients. Where multiple common protocols are supported, user preferences are utilized to determine which of the commonly supported protocols will be utilized for the wireless data session. Once a data session is established, the control channel may be idled periodically to conserve power. Alternatively, the protocol utilized in the wireless data session may be used to transmit control messages using the protocol of the present invention.

摘要： A system and method for wireless cryptographic key exchange among participants in a wireless computing network is presented. This allows the authorized participants in the wireless communication session not have the same key before the wireless computing session begins. This wireless online key exchange/generation is based on a random modulation technique and a domino match. Once the initial modulation scheme is selected, each data transmission includes an indication of what modulation scheme should be used for the next data transmission. If a given number of bits are to be used, the modulation scheme for the final transmission may be limited to complete the bit transfer. The bit value assignments within particular modulation schemes may also be varied for each subsequent transmission.
