Abstract :
There are many requirements for increasing the user capacity in radio wireless communication. Adaptive array antennas are useful for reducing the interference signal. This paper proposes multiuser equalization based on an adaptive array antenna for DS/CDMA. This approach is considered as the joint transmitter and receiver multiuser equalizer in spatial and temporal domains. First, this paper describes the channel model for DS/CDMA in spatial and temporal domains. Then, the proposed system is described. Finally the system is evaluated by computer simulations
