Wavelet Transform Denoising Method for Radio Fuze Signal Processing

Wavelet transform principle and wavelet coefficient threshold denoising method are briefly introduced in this paper. Next FFT method and the wavelet transform method are discussed. Both simulated signal and tested radio fuze signal are denoised by the FFT method and wavelet transform method. Simulation results show that the wavelet coefficient threshold denoising method has higher precision and faster speed than the FFT method.
