| 英文摘要: |
| The mobility of relay has great influence on the performance of a cooperative relay system. This paper proposes a dynamic selection scheme under the amplify-and-forward communication mode in high mobility environment, based on the estimation of channels and the power allocation for each relay node by comparing it with the pre-set threshold. This scheme is used to choose the cooperative relay dynamically for a multiple relay scenario. Simulation results show that this proposed relay selection scheme decreases the outage probability effectively, maintains system capacity well, and improves the performance of the relay system. |
