摘要

A network coding (NC) based two-subscriber-cooperation scheme in a full-duplex transmission mode of orthogonal frequency-division multiple access system is proposed to further improve the network throughput. And a double level Nash bargaining solution (DL_NBS) game is adopted to resolve the inter-user resource bargaining problem. In the inter-user pair, the pairwise capacity based NBS is utilized to allocate subcarrier and distribute power between the cooperative subscribers. Simulations show that the proposed CoNC achieves a system capacity of 49.1% higher than the normal cooperative transmission, and 46.4% higher than the direct transmission. Meanwhile, compared with the traditional resource allocation algorithms, the two-level NBS solution achieves a well tradeoff between fairness and efficiency, and perfectly suits the distributed subscriber cooperation scenario as well.
