This paper investigates the outage capacity performance for cooperative wireless communication schemes over independent nonidentical Nakagami-m fading channels with arbitrary fading parameters. The network consists of multiple dual-hop nonregenerative relays in addition to a direct path to achieve the cooperative diversity with maximal ratio combining at the destination. Closed form expressions for...
The distributed relay selection protocol recently developed by Bletsas et. al. provides a simple and practical mean of achieving cooperative diversity. However, for cooperative networks where relays employ the decode-and- forward (DF) method to send information, it cannot achieve full diversity unless each relay knows whether it decodes correctly or not. Moreover, the criterion used to select the...
One important application of cooperative communications is to extend coverage area in wireless networks without increasing infrastructure. However, a crucial challenge in implementing cooperation protocols is how to select relay-source pairs. In this paper, we address this problem based on the knowledge of the users' spatial distribution which determines the channel statistics. We consider two scenarios...
