| Abstract: | In recent years there has been an increasing focus on the cooperative diversity in wireless communications, the reasonable selection of the relay in cooperative communications can give high-gain. In this paper, we introduce the choose of cooperative timing and the form of cooperative relation, focused on three main methods of relay selection: location-based information, based on the average received signal to noise ratio and based on the instantaneous state channel relay selection algorithm, and then give a... |
