Weights Optimization for MIMO-SDMA System
Zongxin Wang · Fudan xuebao. Ziran Kexue ban · 2004
A joint optimization algorithm of transmitting and receiving weight vectors for MIMO-SDMA system is proposed. This algorithm is based on the idea of symbol cancellation. Using such weight vectors can not only separate the transmitting data of multi-users,but also improve the bit error rate,and maximize the capacity of MIMO channel as well. Simulation results show that this algorithm,compared with other three algorithms,has best performance in MIMO-SDMA system.
