【摘要】 针对自适应双工中继部署在多中继选择系统的场景,提出了一种联合中继选择和自适应双工方案。相比于传统的全双工中继选择方案,其根据瞬时信道条件自适应性地选择合适的中继和双工模式来优化系统整体性能。分析了系统基于SINR的中断概率和平均符号错误率性能。仿真结果表明这种方案消除了全双工模式下的性能门限,提升误码性能,带来分集增益。更多还原

【Abstract】 A joint relay selection and adaptive duplex scheme is proposed for the deployment of adaptive duplex relay in multi-relay selection system.Compared with the traditional full-duplex relay selection scheme,this scheme adaptively selects the appropriate relay and duplex mode according to the instantaneous channel conditions to optimize the overall performance of system. The system outage probability and average symbol error rate performance based on SINR are analyzed. Simulation results show that this scheme can eliminate the performance threshold in full duplex mode,improve the error performance and bring diversity gain.更多还原
