Codeword Automatic Repeat Request/Decoding Method and Transmitting/Receiving Apparatus by Using Feedback Information

The present invention relates to a codeword retransmission / decoding method and a transmission and reception device using the feedback information. The present invention is characterized in the case of an attempt to decode the data received at the receiver fails, the function of transmitting feedback information including the corresponding need success / failure, and the retransmission of the decoded information thereto to the transmitter. According to the present invention, it can be expected an effect that can increase the chances of success of retransmission by repeatedly the code words of the code bits transmitted in a previous transmission for decoding of the retransmitted portion by the receiving unit configured to retransmit the feedback information. Retransmission feedback information, ARQ, error correcting codes, and reliability
