Abstract:

A new scheme of joint iterative decoding design of channelnetwork coding for multiple access relay channel based on studying physical layer’s networking coding in wireless network is proposed, that is the joint iterative decoding design of convolutional Turbo codes (CTC) and network coding. This scheme considers that the relay may not correctly decode the source information, the destination can select the appropriate choice of a priori information for decoding. Simulation result shows this scheme has a stronger error correction performance and more suitable for harsh communication environment, in addition, with the increase of relay and destination’s receiving antenna NR and ND, the error correction performance of the system increases as well, in other words, the proposed scheme can be widely used in the multiple access relay channel environment.
