Abstract
By modeling Multi-user Two-way Relay Network as Weighted Bipartite Graph(WBG)and rational design of weight of the WBG using the channel state information,we make the relay and user-pair selection problem which is aim to maximize the total rate of the system equivalent to the Maximum Weighted Matching(MWM)problem of the WBG. Based on the Hungarian algorithm of graph theory,we proposed the Maximum Weighted Matching Selection Strategy(MWS). In further consideration of MWM and user-pair Fair-ness,we proposed the Maximum Weighted Matching Round-Robin Strategy(MR-RS)and the Maximum Weighted Matching based on Data Sequence Factor Strategy(MDS). The simulation results prove that the three strategies all enhance the performance of the total rate of the system.关键词
