摘　　要：针对多径衰落信道,该文提出了一种基于导频的串行多径干扰抵消技术(SMPIC)和相应的RAKE接收结构,进行了理论分析和计算机仿真,并与常规的RAKE接收进行了比较,结果表明,采用此技术可改善 RAKE接收性能,且结构简单、易于实现。A pilot-based serial multipath interference cancellation method and the corresponding RAKE receiver are proposed. Theoretical analysis and computer simulations are carried out, and comparison with conventional RAKE receiver is performed. It is shown that RAKE receiver performance can be improved using this method with simple structure and easy implementation.
