  • To combat fading in wireless channel, an Opportunistic Relaying scheme based on Physical-layer Network Coding (PNC-OR) is proposed, which not only improves the network throughput by network coding ideas, but also achieves the multi-user diversity gain through relay node selection. Focusing on the bi-directional wireless relaying channels, the sum capacity of the destination nodes in the PNC-OR scheme for the quasi-static fading environment is developed. The numerical results show that in contrast to the opportunistic relaying scheme and conventional network coding scheme, PNC-OR scheme achieves higher spectral efficiency.
