摘要：
In this paper, the diversity-multiplexing tradeoff (DMT) behavior of a novel concurrent decode-and-forward (DF) relaying cooperative diversity transmission protocol is analyzed. A two-source two-relay one-destination scenario is considered in which concurrent transmission among the network nodes is used by combining the two sources' two classic DF relaying steps. Through the DMT analysis, it is shown that the proposed protocol can effectively recover the multiplexing loss induced by the classic DF relaying protocol, while still obtaining diversity gain. The system model is further extended to a generalized M-source network.
