Efficient Transmission Polices For Full-duplex Relay Networks Using Network Coding

In this thesis,efficient data transmission polices for full duplex relay networks using random linear network coding is studied.The main idea is to realize a reliable and efficient data transmission polices on wireless double-hop network by combining the advantages of full-duplex relay mode and network coding technology.In order to improve the system throughput,three data transmission schemes are compared in this paper.Scheme A:traditional ARQ data transmission polices without network coding;Scheme B: data transmission polices based on random linear network coding for packets at base station;Scheme C: data transmission polices based on random linear network coding for packets at full-duplex relay station.We first compare the throughput performance of the three schemes through theoretical analysis,and then verify the validity of the theoretical results by simulation experiment.Theoretical and simulation results show that the proposed data transmission polices using random linear network coding is superior to the traditional ARQ data transmission strategy.Simulation results show that scheme C has the best throughput performance,followed by scheme B and scheme A.In face of the multi-user scenarios,scheme B and C thanks to the network coding technology has better throughput performance compared to the scheme A,and the stability of the scheme B and C is more outstanding,namely when the number of users increase gradually,their performance is slightly lower,and scheme A performance degradation is obvious.
