Network Coding Based Multiple-Hop Efficient Transmission Method for Multiple-User Multiple-Relay Networks

Abstract

A transmission method , combining both the bit error diversity and joint network-channel coding, was proposed for multiple-user multiple-hop multiple-relay networks. In the poposed method, an interleaver was designed for the bit error diversity and a novel protocol was devised for random linear network coding. The proposed method as well as other two methods—Method I without channel code and protection and Method II only with protection, was analyzed by deriving performance expressions in terms of packet error rate (PER) and throughput. Moreover, simulations further prove the superiority of the proposed method. Numerical results show that the proposed method gains an improvement in PER compared with Method I & II and keeps highest throughput within certain range of SNR.
