Abstract

In this paper, an adaptive decode-and-forward (DF) cooperative diversity with multiple-antenna terminals is proposed. The adaptive algorithm is based on instantaneous channel state information (ICSI). Because of time variability of wireless channel, the instantaneous bit error rate (BER) performance of cooperation is not always better than non-cooperation. At the beginning of each frame, whether DF cooperation or direct transmission will be adopted during the frame is decided according to ICSI. Simulation results show that the Adaptive DF cooperative diversity can improve the average BER performance than traditional DF cooperative diversity. Moreover, it consumes less energy and time, and occupies less channel resource.
