这篇文献介绍了在无线协作网络中结合最优中继选择和能量分配的一种能量有效性优化算法，将系统建模成马尔可夫链，再用优化算法进行求解最优中继。-we investigate a distributed joint relay selection and power allocation optimization scheme over wireless cooperative networks

In this paper, an Alamouti-coded decode-And-forward protocol with optimum relay selection for three-user one destination cooperative communications is investigated. Particularly, we design the new protocol that allows the source node retransmitti
