摘　　要：研究了相干解调法和包络检波法(非相干解调法)2种解调方法。在此基础上,提出了一种基于小波的键控调制方法,解决已有的小波调制方法数据冗余过大而导致带宽浪费的问题。仿真结果表明,该方法有较好的抗噪性能。Based on the research on coherent demodulation and non-coherent demodulation, the method of wavelet based shift keying modulation was introduced in this paper, which solved the problem of bandwidth waste caused by too large data redundancy of existing wavelet based modulation methods. The simulation results showed that the proposed method had better anti-noise capability.
