New approach to wiener deconvolution filters design 去卷濾波器設計新方法
The self - tuning white noise wiener estimators and information fusion self - tuning white noise wiener estimators are presented , and self - tuning wiener filter and wiener deconvolution filters for signals are also presented 提出自校正白噪聲wiener估值器和信息融合自校正白噪聲wiener估值器,以及信號自校正wiener濾波器和wiener反卷積濾波器。
We discussed common methods of digital deconvolution and analyzed effects of noise on it . then , we simulated digital deconvolution filters and optimization criteria of filtration parameters . after that , we gave the application of them in the frequency band extension technique 首先,介紹了數字反卷積的常用方法及噪聲對數字反卷積的影響;然后,研究了常用的數字反卷積濾波器及濾波參數的優化準則;最后,給出了數字反卷積在頻帶展寬技術中的應用。
