SYSTEM FOR DETECTING SIGNAL BASED ON PARTIAL MAXIMUM LIKELIHOOD AND METHOD THEREOF

摘要

According to the present invention, a receiver comprises: a partial filter generation unit for selecting a signal as much as a predetermined size among sampled signals, and extracting a filter coefficient with respect to the size of the selected signal to perform QR decomposition on a corresponding filter coefficient; a partial ML setting unit for determining the length and the number of candidate symbol combination of a signal to be detected, and generating a candidate ML symbol combination based on the length and the number of the determined candidate symbol combination; a signal detection unit for detecting remaining symbols from a preset part of the sampled signal based on the generated candidate ML symbol combination; and a final signal selection unit for selecting a candidate symbol which is the closest to the sampled signal among the detected candidate symbols as a final detected signal.
