Abstract

For the application of LDPC in relay channel, a new matrix construction method for LDPC code is presented. The parity bits generated by the relay node are viewed as part of the whole code in the destination thus can be transmitted directory to the destination without the second coding process. The destination decodes the messages from both the source and the relay with a jointed matrix presented in this paper. Experiment results show that new technique can greatly promote the performance of LDPC in the relay channel.
