Abstract
In this paper, we propose a new full-rate cooperative communication strategy in wireless relay networks without direct path between source and destination. This strategy coined full-rate amplify-and-forward (FRAF) utilizes multiple relay nodes to take turns to amplify and forward data package for the transmitter at different time slot. Thus the source node could continue sending without cessation. On the other hand, prevailing linear constellation precoding process is adopted at the source node to solve the problem caused by the imbalance of the error performance of the data sent at odd and even time slots. Furthermore, we analyze the outage probability and certificate that FRAF strategy can achieve the full diversity gain. The simulation results indicate that FRAF could improve the performance of the system effectively compared to the conventional amplify-and-forward (AF) and decode-and-forward (DF) strategy.
