摘　　要：传统的RAKE接收机能够在一定程度上检测合并多径干扰,但在多径数大于分集数时性能下降。文中提出一种自适应RAKE接收机,在多径数大于分集数时明显提高了RAKE接收机的性能。In order to achieve reliable communications through multiple - access channels, especially when the number of multipaths is larger than RAKE fingers, adaptive RAKE receiver is proposed. Simulation results, over Rayleigh frequency selective fading channels indicate the benefits of BER over adaptive RAKE receivers.

关 键 词：自适应RAKE接收机 多径数 分集数 递归最小二乘算法
