| Abstract: | The paper deeply studies the procedure of WCDMA Downlink receiver and describes the fundamentals of DS-CDMA receiver. After comparing and analyzing some algorithms, and utilizing the statistic characteristics and approximate-relation of received signals and considering the realization complexity and computation, we propose an improved WCDMA downlink receive algorithm with high practical value. Simulation results have proven that the algorithm has perfect performance. |
