Selective Cooperative Schemes Using Quasi-Cyclic LDPC Codes over Rayleigh Fading Channels

摘要：

Cooperative communication enables distributed terminals with a single antenna to form a virtual multiple antenna system and benefits from diversity. In this paper Quasi-Cyclic LDPC codes are applied to both Amplify-and-Forward Cooperative scheme and Decode-and-Forward scheme over Rayleigh fading halfduplex relay channel. Simulation results show excellent performance of Quasi-Cyclic LDPC codes with cooperative schemes compared to the same codes in direct link communication of AWGN channel and Rayleigh channel. Compared to Amplify-and-Forward scheme, it is shown that Decode-and-Forward scheme is more sensitive to the path-loss fading.
