Efficient Scheduling Scheme for Multi-Way Relay Systems With Physical-Layer Network-Coding
In this paper, the authors propose a novel scheduling scheme which can be employed for multi-way relay systems. This new scheme is based on the Physical-layer Network Coding (PNC). To evaluate their proposed scheme, the Bit-Error-Rate (BER) and throughput metrics are analyzed for the multi-way relay systems enduring both channel fading and Additive White Gaussian Noise (AWGN). Moreover, numerous Monte Carlo experiments are undertaken to compare their proposed new scheduling scheme with other existing strategies. The simulation results demonstrate that their proposed scheme is much more efficient than other existing methods.
