摘要 采用线性并行干扰抵消作为多用户检测方法,结合天线阵列,提出一种新的接收机结构.由天线阵列接收的信号经过并行干扰抵消后,采用自适应算法,根据最小均方误差准则,得到软判决用户数据的加权系数.计算机仿真结果表明,这种接收机结构具有较好的抗多径性能. A new CDMA receiver that combining multistage parallel interference cancellation as an multiuser detection method and antenna array is given. According to MMSE criterion, the weights can be found by adaptive algorithms, that is used to combing the softdecision output user data after multistage parallel interference cancellation processing and antenna array receiving. The computer simulation result is given, it explains the good performance of this receiver to resist multipath effect.
