Prefilter design by spectral factorization |
摘要 |
A baseband signal processing method for calculating minimum phase prefilters. The method preferably utilizes a spectral factorization approach. The prefilter is constructed from a minimum phase version of an estimated channel impulse response. Complex valued filter coefficients are determined by solving a system of linear equations for each iteration of the spectral factorization. The constructed prefilters provide equalization in both the forward and backward directions.
