Abstract: Disclosed is a receiver including: a partial filter generating unit selecting a signal as large as a predetermined magnitude among sampled signals and extracting a filter coefficient for the selected signal magnitude to perform QR resolution for the filter coefficient; a partial ML setting unit determining the lengths and the number of candidate symbol combinations of a signal to be detected and generating a candidate ML symbol combination based on the determined lengths and number of candidate symbol combinations; a signal detecting unit detecting residual symbols in a predetermined part of the sampled signal based on the generated candidate ML symbol combination; and a final signal selecting unit choosing a candidate symbol closest to the sampled signal among the detected candidate symbols as a finally detected signal.
