Cooperative Transmit Diversity Based on Physical Layer Network Coding

摘要：

We propose a new strategy for cooperative transmit diversity based on physical layer network coding and multiuser detection. Physical-layer Network Coding (PNC) exploits interference, instead of avoiding it, all source nodes transmit simultaneously to significantly enhance network throughput. The scenario under consideration is one in which two source nodes A and B transmit information to a common destination node D. Simulation results show that our new scheme outperforms traditional cooperative diversity based on decode-and-forward about 1.5 dB in terms of frame-error-rate (FER) but less complexity.
