摘要
码分多址个人通信系统（ＣＤＭＡ－ＰＣＮ）中抗多径干扰技术的研究具有重要的意义。在ＣＤＭＡ系统中采用多径分集（ＲＡＫＥ）接收是抗多径干扰的一种有效方法，即通过相关解扩技术进行多径分离，再根据某种准则组合，达到改善抗干扰特性的目的。在对几种ＲＡＫＥ接收方案进行分析的基础上提出的以导引信号为探测信号的自适应多径分集接收（ＡＲＤＰ）实验系统的设计方案，经实验验证具有可行性。
This paper analyzes anti-multipath interference technology in CDMA-PCN system. By using RAKE receiver we can distinguish several multipath signals, then combine them through certain criterion to improve signal's anti-multipath interference quality. Based on RAKE receiver theory and several RAKE receiver schemes, we propose the adaptive RAKE detection based on pilot (ARDP) experimental system. Through experiments, we assure that this system is applicable.
