摘　　要：针对辨识数据的处理问题 ,提出了基于小波分析的数据处理方法。对于含噪声数据的噪声未知时 ,可以通过小波高频分解系数估计出噪声的强度 ,进行数据滤波。该方法简单且去噪效果好 。For the problem of identification data processing, in this paper, a novel method based on wavelet analysis for data processing is proposed. When noises of data are unknown, wavelet decomposition coefficients in high frequency are used to estimate the amplitude of noises and filtering is in process. This method is simple and has good denoising results, simulation results show that the method proposed in this paper is efficient.
