Patent ID: 8077758

Claim:
A spread spectrum communications system comprising: an antenna array comprising N antenna elements for receiving different summations of desired and undesired signals, where N≧2; a plurality of receivers, each receiver coupled to said same antenna array and operating based upon a respective channel code for de-spreading the desired and undesired signals for determining at least one desired signal associated with the respective channel code, and combining the at least one desired signal and the undesired signals after the de-spreading; a processor coupled to said plurality of receivers for forming a mixing matrix based upon the combined signals from each receiver, with entries on a diagonal of the mixing matrix corresponding to the desired signals and entries adjacent the diagonal corresponding to the undesired signals, and processing the mixing matrix so that a level of the desired signals increases and a level of the undesired signals decreases; and a demodulator coupled to said processor for demodulating at least one desired signal and determining an error rate of the at least one desired signal after demodulation, the error rate being used as feedback to a transmitter transmitting the at least one desired signal so that characteristics in new transmitted signals can be adjusted based upon the determined error rate.
