In this paper , we proposed three dfs algorithms for them which finally are testifed by example . accordingly , we get the method and conclusion for double channel deconvolution 本文分別對(duì)上述三類情況進(jìn)行分析和推導(dǎo),得出各自相應(yīng)的求解算法,最后通過(guò)實(shí)際例子對(duì)三種算法進(jìn)行了驗(yàn)證。
In this paper , based on the study of single channel deconvolution , we made a research in double channel deconvolution . there are three cases when we find its results by dfs algorithm . the first is that z transform expression of results have no polar on the identity circularity . the second is that denominator have zero on it while molecular have zero to counteract . the third is that z transform expression of results have polar on it , which is well known that deconvolution kernel has no spectral inverse 本文在對(duì)雙通道信號(hào)卷積反演求解時(shí)采用較為簡(jiǎn)便的dfs算法,在求解過(guò)程中會(huì)遇到的三類情況,第一類是解的z變換表達(dá)式在單位圓上無(wú)極點(diǎn),第二類是z變換表達(dá)式分母有零點(diǎn)但分子有相應(yīng)的零點(diǎn)作抵消,第三類是z變換表達(dá)式在單位圓上有極點(diǎn)(即稱之為卷積核無(wú)譜逆) 。
In recent decades , people have made a research in single channel deconvolution problems , for example , the traits , fast algorithm of deconvolution results and process for error . they proposed many methods , such as inverse filter algorithm , z transform algorithm , dfs algorithm , l2 algorithm , recursion algorithm 幾十年來(lái),人們對(duì)單通道信號(hào)卷積反演問(wèn)題如反卷積解的性質(zhì)、解的快速算法及對(duì)誤差的處理等進(jìn)行了深入的研究,并取得了不少的成就,如逆濾波法、 z變換法、遞歸法、 dfs法、最小平方法等。
