Multiple-access decode-and-forward relaying with iterative detection and decoding

In this paper, we propose a novel protocol for cooperative diversity based on decode-and-forward (DF) with iterative detection and decoding (IDD) receiver. Closed-form expression of outage probability is derived under quasi-static fading channels. Numerical results show that the proposed scheme achieves higher diversity order than traditional DF scheme without additional transmitter power.
