摘    要:提出一种多径衰落信道下DCSK通信系统的延迟合并接收方案. 理论分析和仿真结果证实了该方案的误码性能. 结果表明,和原DCSK通信系统相比,使用了延迟合并接收方案的DCSK通信系统误码性能有所提高;不同接收路径延迟对应的误码性能基本相同;各接收路径采用等增益合并方式时误码性能最好;其理论上限随着接收路径数增加而逐渐降低.

关 键 词:DCSK通信系统  多径衰落  延迟合并  误码性能

Abstract:A delay-combining reception scheme for DCSK communications system over a multipath fading channel is proposed. BER performance of the scheme is analyzed theoretically and simulated. The results indicate that in comparison with the original DCSK communication system, the one with delay-combining reception has better BER performance. When the delays of reception paths are different, the BER performance are almost the same. When equal gain combining is adopted for the reception paths, the scheme achieves the best BER performance. The theoretical upper bound of the BER performance decreases with the increase of the number of reception paths.
Keywords:DCSK communication system  multipath fading  delay-combining  BER performance
