摘　　要：提出用于多径 CDMA信道下的盲空时多用户检测器 ,它具有同时抑制多址干扰 (MAI)和多径畸变 (MPD)的功能 ,利用最小均方算法 (L MS)和自适应向量跟踪算法分别实现自适应盲多用户检测和多径接收信号的最佳结合。最后给出计算机模拟结果 ,验证了模型及算法的可行性。In this paper, the authors introduce a detection scheme for adaptive suppression of multiuser interference (MAI) and multipath distortion(MPD) in multipath CDMA channels. The authors provide an adaptive blind multiuser detecting and optimum combining implementation for the two parts of the proposed receiver, based on the least mean square(LMS) algorithm and an adaptive vector tracing algorithm respectively. Finally, the feasibility of the above model and algorithms are proved by the numerical results provided by computer simulation.
