| 摘 要： | 在正交频分多址接入两用户协作中继系统中，为进一步提高协作系统的吞吐量，提出在协作节点处运用网络编码(NC)进行全双工协作通信的传输方案. 同时，引入纳什议价均衡(NBS)博弈，考虑协作用户吞吐量均衡，设计了双层纳什议价均衡(DL_NBS)博弈来协调用户对间的子载波和功率分配. 仿真结果表明，基于NC协作系统方案的吞吐量比普通协作传输模式提高约491%，比直传模式提高约464%；DL_NBS博弈资源分配方案与传统资源分配算法相比，不仅更适用于分布式用户协作场景，且能取得公平性和有效性的折中.

| Abstract: | 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 Co... |
