摘要
在互补序列理论的基础上,讨论了基于一种新型的扩频序列 修正互补序列单用户CDMA系统加修正的算法,并分析了其抗多径干扰特性.在理论分析的基础上,给出了配合使用DSP与FPGA的实现平台,介绍了两者的通信接口设计与加修正算法的具体实现流程.实现结果证明了本文提出的利用互补序列加修正来抑制多径干扰的理论具有实际意义.
The modified complementary series which is produced according to the OND (orthotropic noise detect) principle is proved to have good antiinterference performance and has been applied to CDMA communication system. A hardware testbed based on DSP&FPGA to implement the algorithm and the software solution is presented. Experiments show that modified complementary series is effective in improving the antiinterference performance in CDMA system.
