Abstract

In this paper, practical cooperative diversity schemes are proposed and investigated. The outage probability is used to evaluate four constant-power decode-and-forward cooperative schemes: Pre-Select One Relay, Best-Select Relay, Simple Relay, and ST-Coded Relay. Two new methods for improving these approaches, called simple distributed power allocation and m-Group ST-Coded Relay, are proposed. It is shown that the performance of Simple Relay and ST-Coded Relay is improved significantly by employing the proposed power allocation without an increase in implementation complexity. Similarly, m-Group ST-Coded Relay gains in lower complexity with only a slight degradation in performance. Performance of the various schemes in a network is evaluated through the link-failure probability. © 2005 IEEE.
