摘要：A spread spectrum communications system includes an antenna array forreceiving different summations of desired and undesired signals, and receivers arecoupled to the antenna array. Each receiver operates based upon a respective channelcode for de spreading the desired and undesired signals for determining at least onedesired signal associated with the respective channel code, and for combining the at leastone desired signal and the undesired signals after the de-spreading. A processor iscoupled to the receivers for forming a mixing matrix based upon the combined signalsfrom each receiver, with entries on a diagonal of the mixing matrix corresponding to thedesired signals and entries adjacent the diagonal corresponding to the undesired signals.The processor also processes the mixing matrix so that a level of the desired signalsincreases and a level of the undesired signals decreases. A demodulator is coupled to theprocessor.
