Method and Apparatus for Error Correction in Multiple-input Multiple-output Communication System

摘要

The present invention relates to a device and method for performing forward error correction in a multiple-input multiple-output communication system using a turbo-blast method. Performing a soft decision with respect to the frames that are received via multiple antennas according to the present invention, the iterative decoding by the soft-decision result of using a priori information a predetermined number of times said frame and symbol of each of reliability that make the frame the output, and encoding the information bits of the decoded frame, and comparing the encoded parity bits and parity bits of the decoded frame, and the comparison result, the encoded parity with the parity bits of the decoded frame If the bits are determined to match, and if the error did not occur, and outputs the information bits do not match to a pre-feedback information of the soft-decision for the reliability and performs repeating the entire process. ; Error correction, CTC encoder, Turbo-BLAST
