Title:
MODELING METHOD FOR SPATIAL FILTER
Document Type and Number:
WIPO Patent Application WO/2020/000979
Kind Code:
A1
Abstract:
A modeling method for a spatial filter. The modeling method for the spatial filter comprises: obtaining the formula of a self-adaptive filtering algorithm (202); and changing the formula of the self-adaptive filtering algorithm to be a pipelined self-adaptive filtering algorithm formula, wherein by means of the pipelined self-adaptive filtering algorithm formula, a current expected signal is estimated on the basis of an input signal and an error signal before a predetermined time so as to realize parallel computing (204). By means of the method, a delay relaxation technique and a sum relaxation technique are used, and a serial algorithm is changed to be a pipelined self-adaptive filtering algorithm that can be processed in parallel, so that a filtering speed is greatly improved by means of parallel computing.
