摘要: 为了更好地实现激光侦听中的语音降噪，采用一种改进的小波阈值去噪算法，进行了理论分析和实验验证，取得了一系列仿真数据。结果表明，改进后的算法与传统的降噪算法相比，降噪后的语音信噪比显著提高，降噪效果明显，信号波形更加平滑、失真度小。Abstract: In order to get better denoising result in laser interception, an improved wavelet threshold denoising algorithm was proposed. Through theoretical analysis and experimental verification, a series of simulation data were obtained. The results show that, compared with the traditional denoising algorithm, the speech signal-to-noise ratio after denoising is improved greatly. Denoising effect is obvious, signal waveform is smoother and distortion is less.
