| Abstract: | 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. |
