To improve the bandwidth efficiency of the classical orthogonal cooperative transmission scheme while maintaining the cooperative gain, a novel non-orthogonal amplify-and-forward cooperative scheme based on distributed space-time code is proposed. In this scheme, the orthogonal characteristic of Alamouti space-time code is utilized to make cooperative users relay on the shared channel resources so...
This paper investigates three kinds of cooperative communication strategies, they are the traditional cooperative forwarding strategy, network coding cooperative communication strategy and space-time block coding (STBC) cooperative communication strategy. The outage probability and bit error rate (BER) of these three kinds of communication strategies were researched. The simulation results show that,...
In this paper, we present a new outage probability analysis of a cooperative system with single antenna terminal. We first introduce the cooperation protocol of the presented scheme. Then, in the destination node, maximal ratio receiver combining (MRRC) and the maximum likelihood (ML) detection algorithm are applied to decode the received signal with the utilization of the signal received from the...
