| Abstract: | A waveform detection method of the pulse signals based on wavelet analysis is put forward. This method can implement the detection for pulse signal waveform parameters by using the modular maximum of wavelet transform. By comparing various wavelet functions, Gaussian wavelet is used to detect the waveform parameter of pulse shaping signal. Theoretical analysis and simulation results show that this method has higher adaptability for Gaussian noise channel environment, lower computational complexity and more accurate estimation and better prospect in engineering applications. |
