Abstract：In order to solve the weakness problem of human ears in multiplexed Morse telegraph's interception and decoding, a method of automatic decoding and separation of multiplexed Morse telegraph based on wavelet transform has been proposed, including a brief analysis of its feasibility and advantages.The method uses the wavelet transform directly to lock the frequency of Morse telegraph and automatically completes the multiplexed Morse telegraph signal separation,and combined with the structural characteristics of Morse telegraph itself, it can realize the automatic decoding function of multiplexed Morse telegraph signal.The results of the experiment show that it is feasible to use the wavelet transform method to process the multiplexed Morse signal and has the practical value.
