Performance analysis of Turbo code and trellis BICM-ID on PNC over impulsive channel

摘要：

　　Physical-Layer Network Coding(PNC)employed on a two-way relay channel(TWRC)is an active research area due to potential doubling of the throughput compared with traditional routing.In this paper,we investigate the effects of impulsive noise added at the relay and sink nodes of a TWRC employing link-by-link coded PNC.The Gaussian mixture model is chosen to model the impulsive noise and the performance of BICM-ID and turbo codes on the TWRC is evaluated through simulation results and extrinsic information transfer(ExIT)charts for different mixtures of impulsive noise.It is shown that with increasing impulsiveness,a PNC system with BICM-ID codes with actually outperforms a comparable PNC system with turbo codes,where both coding schemes have the same block size,code rate and constraint length.
