Blackman窗插值的小波模极大值去噪算法
Denoising algorithm of wavelet modulus maximum based on Blackman window interpolation
摘要
Abstract
The Blackman window interpolation algorithm is put forward, the signal modulus maxima are obtained by Ad Hoc algorithm, the signal estimated coefficients of wavelet can be obtained from the interpolation of Blackman window be-tween the modulus maxima points of signal and reconstruct signal by the signal estimated wavelet coefficients. The simu-lation results demonstrate that the novel algorithm with the fast speed of modulus maximum direct reconstruction algo-rithm and the accuracy of alternating projection algorithm, improves the SNR and reduces the distortion.关键词
