大多数去噪方法只能对高斯噪声或某一类有色噪声进行去噪处理.提出一种新的相位匹配噪声估计的高阶谱去噪方法,利用该方法既可以去除高斯噪声又可以去除非高斯噪声,通过高阶谱和相位匹配实时的逼近当前噪声,建立二次去除噪声方法,通过实验证明该方法能够非常明显的去除高斯与非高斯噪声,在无法分出噪声的种类情况下进行信号的去噪,取得非常好的去噪效果.
Most denoising methods can only denoise Gaussian noise or some kind of colored noise.A new high-order spectral denoising method for phase-matched noise estimation is proposed, which can remove both Gaussian noise and non-Gaussian noise Gaussian noise, high-order spectral and phase matching real-time approximation of the current noise, the establishment of secondary noise removal method, the experiment proved that the method can be very significant removal of Gaussian and non-Gaussian noise, the type can not be separated into the signal noise Of the noise, made very good denoising effect.
