摘要：

Cooperative communications is a promising technology to improve the performance of wireless sensor networks. In this paper, we propose a novel relay selection scheme combined with feedback and adaptive forwarding in cooperative communication systems. A closed form expression for the tight lower bound of its outage probability is derived and a detailed analysis of its diversity-multiplexing-tradeoff (DMT) performance is presented Simulation results demonstrate that our method outperforms a variety of existing relay selection schemes in terms of outage performance(1).
