摘要
提出了一种基于符号抵消的多用户MIMO系统发送和接收权向量联合优化算法,使用这些权向量不但可以实现多用户的传输数据分离,还可以改善系统的误码率性能,并使信道容量最大化.模拟结果表明,相比较其他3种算法而言,使用本算法的MIMO SDMA系统拥有最佳性能.
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.
