In this paper, the performance of adaptive relaying schemes in cooperative diversity (CD) systems equipped with automatic repeat request (ARQ) is studied. Both selection relaying and incremental relaying are considered with a regenerate and forward CD system. The performance metrics of the CD-ARQ system such as efficiency, packet drop rate, average delay and jitter are presented. Numerical results show that selection relaying with a good partner outperforms incremental relaying. In addition, selection relaying performs better than incremental relaying without the ARQ scheme.
