Abstract
According to the characteristics of MSK signals, detecting statistics about mean ratio and variance ratio of the modulus which is calculated by normalized and non-normalized amplitude through Haar wavelet transform is established. Between-classes and within-classes modulation recognition of MSK signals through the relationship of minimum frequency interval and code rating and the ary of the signal is fulfilled. And this method is validated through software simulating. The simulation results show that the recognition method based on wavelet transform can recognize MSK signals correctly in the condition of low SNR.
