摘　　要：提出了一种将空时MLSE算法用于判决反馈检测器的方案,它无须功率控制即可实现抗远近效应,其误码性能比广泛应用的多用户检测中的判决反馈器理想,它可用于CDMA移动通信系统中.经计算机仿真可以看出,这种方案确实对系统的接收性能有一定的改善.A new method was proposed to combine the spacetime MLSE receiver with the decisionfeedback detector to realize the nearfar resistance without power controlling,thereby making the bit error rate of a decisionfeedback receiver better than that of the widely applied decisionfeedback detectors,which can be applied to CDMA mobile communication system.Computer simulation shows that the method can effectively improve the receiving function of the system.
