The Traits And Algorithm Of Double Channel Deconvolution

With DSP being popularized and applied, deconvolution has found its application in many fields , such as optical imaging, image restruction , system discrimnation, signal restoration. Now deconvolution has been a special topic in DSP and its application has entered a new stage. 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. 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. 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.
