  • 脉搏信号降噪
    文基于小波分析的特点,提出了一种对信号进行多重小波 变换的自适应去噪法,该方法不仅克服了小波去噪软硬阈值法的局限性,而且解决了自适应滤波中参考信号选取难的 问题,将该方法用于脉搏信号降噪,得到了满意的去噪效果。(The text features based on wavelet analysis, proposed an adaptive multi-wavelet transform for signal denoising method, this method not only overcomes the limitations of hard and soft thresholding method of wavelet de-noising, and resolve the reference signal adaptive filtering Select the difficult problem of the method is used to the noise of the pulse signal, and been satisfied with the denoising effect.)
