Abstract

In this work, we study the performance of rate-compatible punctured convolutional (RCPC) coded cooperation system. Theoretical bit error probability is deduced over slow Rayleigh fading channel based on the characteristics of RCPC codes and coded cooperation. The coded cooperative system obtains two inherent benefits, such as achieving the spatial diversity offered by the relay channel and also the coding advantages provided by the RCPC codes and coded cooperative system. Performance improvement of the coded cooperative system is also provided at last, compared with amplify-and-forward scheme and non-cooperative scheme.
