Abstract :
This paper compares the performance of several transmit and receive signal processing technique, such as Rake, multiuser detection, Prerake and transmit filters. Those techniques are used to eliminate multipath interferences or multiple access interferences or both. We illustrate the raw bit error ratio of those technique based on different spreading codes and different number of antenna elements. The result can be used to select which technique to be used in the DS-CDMA systems under different request.
