摘　　要：针对直接序列码分多址(DS-CDMA)的多输入多输出(MIMO)系统,设计了几种天线结构,提出利用空时分组码分别进行空时线性多用户检测和空时串行干扰对消多用户检测.通过分析误码率和算法的复杂性,比较了这两种方法的性能.仿真结果表明,空时线性多用户检测方法优于空时串行干扰对消多用户检测方法.This paper designed several antenna configurations for DS-CDMA communication in multiple input multiple output (MIMO) systems. After the transmit symbols are encoded as space-time block codes, space-time linear multiuser detection and space-time serial interference cancellation multiuser detection are simulated. The performances of the two methods are compared via analytical bit-error-rate calculations and computation complexities. The simulation results show that the space-time linear multiuser detection outperforms the space-time serial interference cancellation multiuser detection.
