| 摘 要： | 提出一种带可调权值的非相干CSK（chaos shift keying）通信系统，分析了其在多径信道环境下的理论误码性能并仿真，结果表明系统的误码性能较好。当权值满足一定条件时，系统的多径误码性能和DCSK（differential chaossllift keying）通信系统的相同，并且其AWGN（加性高斯白噪声）误码性能优于一些已有的非相干CSK通信系统。

| Abstract: | A noncoherent CSK communication system with adjustable weights was proposed. Both theoretical analysis and simulation for its BER performance under the environment of multipath channels were studied. The results show that the BER performance of the system is good. When the weights meet certain requirements, the multipath BER performance of the proposed system is identical to that of the DCSK communication system and its AWGN BER performance is better than those of some existing noncoherent CSK communication systems. |
