摘要
结合CDMA中的多载波技术,介绍了无线通信中的正交全补码编码原理,给出了基于正交全补码的多载波CDMA系统特点,计算机仿真结果表明,正交全补码具有更好的性能。文章追踪了CDMA系统编码领域的最新动态,并在最后给出了正交全补码的CDMA系统的多径信号接收技术。
Principles of orthogonal complementary codes in wireless communication field are described together with multicarrier techniques of CDMA system in this paper. Features of a multicarrier CDMA system based on orthogonal complementary codes are presented. The simulation result showed that the performance of orthogonal complementary codes have more advantages than other codes. Some new developments in CDMA system coding filed are focused on. Finally multipath signal reception techniques of CDMA system based on orthogonal complementary codes are demonstrated.
