Performance analysis of outage probability and diversity-multiplexing tradeoff for two-path relaying cooperative communications
Enyu Li · Journal of Computer Applications · 2012
In order to improve the spectral efficiency and outage performance of the cooperative communication system,a Two-Path Relaying(TPR) cooperative communications model based on the Decode-and-Forward(DF) protocol was proposed.Meanwhile,two data transmission modes were presented for the proposed system.The closed-form expressions for outage probability and the relations between diversity gain and multiplexing gain were derived.The simulation results show that,compared with the conventional two-relay DF protocol,the outage probability performance of the two proposed transmission models is greatly improved.
