| 摘 要： | 针对集中控制中继选择算法为获取瞬时信道状态信息开销较大的问题,受分布式算法的启发,本文提出了一种半分布式中继选择算法.在这个半分布式算法中,每个中继节点自己决定是否能参与协作,而从多个可能的节点中选择最优节点的最终决定是通过基站来完成的.由于在不同的节点之间不需要信道状态信息的交换,本文的算法易于执行,更适用于实际的网络.实验结果表明,该算法能够获得较好的分集效果.

| Abstract: | Aimed at the problem that the spending of centralized control relay selection algorithm for obtaining the instantaneous channel state information is large,inspired by distributed relay selection algorithim,an effective Semi-Distributed relay selection algorithm is discussed for decode-and-forward wireless relay networks.In the proposed algorithm,each relay node can make decision on its feasibility individually,and the ultimate decision on the relay node selection among multiple feasible ones is made in a ce... |
