Joint optimization of both signature sequences and linear receiver filters for a downlink DS-CDMA system with multipath propagation channels is considered. The signature sequences and the receiver filters are optimized in order to minimize the sum of the mean-squared-errors at the output of the receivers while maintaining a fixed total transmitting power. The signature sequences and receiver filters are derived using a filtering approach to accommodate for the multipath propagation effects.
