Abstract

A new physical-layer network coding (PNC) scheme is proposed for asymmetric two-way relay channels (TWRC). In the scheme, the two source node employ orthogonal carriers and the relay node employ orthogonal combining, instead of XOR, which is used in most PNC schemes. Our proposed scheme is named as combined orthogonal physical-layer network coding (COPNC). COPNC can provide better BER performance than PNC and orthogonal PNC (OPNC) when the channel conditions in TWRC are asymmetric.
