| 摘 要： | 为减少系统反馈数量,提出一种基于门限的中继选择方案.每个中继根据测得的瞬时信道信息与门限比较,判断其可用性,并由基站为每个终端从多个可用中继中确定一个最佳中继.仿真结果表明,该方案可与蜂窝网中所用的中继选择方案获得近似相等的容量,但其复杂度大大降低.该方案可获得的容量明显优于随机选择方案和直传方案.

| Abstract: | To reduce the number of feedback,a threshold-based relay selection scheme was proposed.Every relay node can determine its feasibility by comparing its instantaneous channel information with the threshold,and the final decision on the relay selection among multiple feasible nodes was made by the base station.Simulation results show that the proposed scheme can provide almost equivalent capacity with that of the previously proposed relay selection scheme in cellular networks,but its computational complexity i... |
