Abstract :
This paper proposes an algorithm of joint transmit and receive weight vectors optimization in MIMO-SDMA system. This algorithm is based on the symbol cancellation method. Using these weight vectors can not only separate the transmit data of multiusers, but also improve bit error rate and maximize the capacity of MIMO channel. Comparison between this algorithm and other three algorithms is also presented. Simulation results show that this algorithm in MIMO-SDMA system has best performance.
