Efficient scheduling scheme for multi-way relay systems with physical-layer network-coding

In this paper, we 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 our 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 our proposed new scheduling scheme with other existing strategies. The simulation results demonstrate that our proposed scheme is much more efficient than other existing methods.
