Abstract

We derive the transmit Wiener filter for DS-CDMA systems which depends upon the noise power at the receivers. We show that the transmit Wiener filter converges to the transmit matched filter and the transmit zero-forcing; filter for low and high signal-to-noise ratio, respectively. Simulation results show the superiority of the transmit Wiener filter compared to the other two transmit filters. Moreover, we observe that the application of the three transmit filters and the respective receive filters lead to similar results.
