摘要：
An improved wavelet method is presented for TWT signal denoising, in which linear-hard and nonlinear-soft threshold regions are defined and given. In MATLAB simulation, Doppler signal affected by 7 dB of additive-white Gaussian noise is analyzed and denoised The results show that signal to noise ratio is 24.2362 and root mean square error is 0.4356, and the improved method is better than the conventional methods.
