Abstract:

A new signal reception method, multipath interference exchange reduction (MIXR), that reduces multipath interference in direct-sequence code division multiple access (DS-CDMA) systems is described. This method uses a despread signal at a timing correlated with the interference in the conventional despread signal before RAKE combining. It is especially effective in the downlink receiver of DS-CDMA systems in which the downlink signals of all users are received with the same fading channels. One computer simulation showed that the BER of the proposed method is 1-2 dB better than that of a conventional RAKE receiver. Other simulations showed that the MIXR receiver is more sensitive than conventional RAKE receivers.
