摘要： A powerful new class of methods for encoding digital data for reliable transmission over unreliable communication channels is described. With this method, the message bits are divided into multiple submessages and the bits in each layer are encoded using a standard error correction code to provide a plurality of subcodewords. A first linear transformation is applied to each of the subcodewords. The so-transformed subcodewords from the different submessages are then combined to form a first redundancy block to be transmitted. Additional redundancy blocks are generated by repeating this process on the same message but with jointly related nonidentical sets of linear transformations. The result is a set of codewords for each message which are then used to generate a transmitted waveform in one of several different ways, depending upon the application. For example, the codewords can be used in sequence (temporally) to form a rateless code for transmission over channels of unknown quality, in which case a receiver accumulates as many of the codewords as are necessary to successfully decode. As another example, the codewords can be spatially distributed if the channel has multiple-inputs, as would be the case in a multi-antenna system. As still another example, the codewords can be distributed over subchannels in a frequency-division multiplexing system.

摘要： A method and apparatus is described for modifying a smart antenna processing strategy determined from a set of signals received at an array of antenna elements of a wireless station, such as a set of weights for processing received antenna signals or forming a set of antenna signals for transmission. The method and apparatus uses the signatures of one or more interferers to produce a modified processing strategy that improves the nulling to the one or more interferers in that, when the modified strategy is applied on the downlink, the transmit signal strength in the direction of the one or more interferers is decreased, and, when the modified strategy is applied on the uplink, the sensitivity to signals from the direction of the one or more interferers is decreased.

摘要： Adapting characteristics of a video stream. A source video stream is received comprising instructions to employ at least one reference frame at a video adaptation device, wherein the source video stream is encoded. The source video stream is adapted, at the video adaptation device, such that the instructions are adapted to store a different number of reference frames. A video stream is produced with the different number of the reference frames.
