A joint design of network coding and channel coding for multiple access channel

Abstract

Network coding is becoming more and more popular in recent years for its ability to improve largely network throughput and robustness. In this paper, a joint physical network coding and channel coding implementation design for multiple-access channel is proposed. It takes advantage of the linearity of LDPC and network coding and SISO module, not only can reduce the complexity of codec, but also can obtain a good performance even in the high SNR. The simulation results show that the proposed design is easy to implement and its performance is close to the Upper limit of the channel capacity, and it can achieve 1.6 times gain over the traditional design.
