In this paper, we consider coding schemes designed for multi-source cooperation, where a cluster of sources cooperatively communicates with the destination. More explicitly, we propose both a powerful superposition coding scheme and a physical-layer algebraic network coding scheme. Our simulation results demonstrate that both of the proposed schemes are capable of performing close to the outage probability bound. Compared to the superposition coding scheme considered, the proposed algebraic network coding arrangement imposes a much lower complexity at the cost of a slight performance degradation, while maintaining the same throughput and delay.
