INTERFERENCE-REDUCED RECEIVER APPARATUS

摘要

There is provided an interference-reduced receiver apparatus wherein sufficiently precise weights can be determined in a short time to contribute to realization of a higher-rate, larger-capacity wireless system. It is another purpose to provide means for deciding an effective timing at which to eliminate interferences. The interference-reduced receiver apparatus despreads received signals at a plurality of predetermined timings, then multiplies the signals as despread by predetermined weights, and then adds them together, thereby demodulating the signals. The interference-reduced receiver apparatus includes weight producing means for determining the weights by use of a product of a signal correlation matrix of the received signals and a channel response vector.
