DECISION FEEDBACK EQUALIZER FOR DIGITAL TELEVISION RECEIVER, AND METHOD FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a decision feedback equalizer for a digital television receiver, and a method for the same. SOLUTION: In the digital television receiver, a TCM decoder may decode a distortion compensated signal to generate symbol decision results and a soft information signal. A decision feedback equalizer may select boundary levels of a non-uniform quantization using a soft information signal delayed only by a 12-D symbol interval. The distortion compensated signal may be generated from a feedback-filtered signal using the symbol decision results. COPYRIGHT: (C)2006,JPO&NCIPI
