摘要： A method for communication includes generating one or more data streams for transmission to respective target receivers, and one or more jamming streams. At least one parameter, selected from a group of parameters consisting of power ratios for allocation to the jamming streams and Modulation and Coding Schemes (MCSs) for assigning to the data streams, is calculated based on a criterion that is set to reduce a probability of the data streams being decoded by at least one eavesdropping receiver. The data streams and the jamming streams are transmitted using an antenna array while applying the at least one parameter.

摘要： The present invention discloses a novel scheme of performing frequency domain filtering that does not require a Hilbert transform and which is faster than equivalent FIR filtering schemes. Such a scheme has applications in implementing filters in voice band modems on OSP platforms and in numerous other applications as well. The scheme of the present invention is shown to be superior in term of CPU resource consumption and memory storage space when compared with an equivalent implementation using prior art time domain convolution techniques. The scheme of the present invention permits the delay buffer in the far end echo canceler to store the signal in real format rather than complex format, thus reducing memory requirements by half. The present invention implements a real to analytic fast convolution in the frequency domain which uses zero CPU resources.

摘要： System and method for backoff correction of channel quality information (CQI). A correction factor is calculated based on a goodness measure such as packet error rate (PER). The selection of modulation and coding scheme (MCS) is made considering the channel quality information (CQI) adjusted by the correction factor. A meaningful goodness measure can be imposed if the goodness measure is very low. A different correction factor can be calculated for different confidence levels, MCSs and transmission modes.
