The illustration of the proposed joint resource allocation and network coding transmission scheme for two-way relay OFDM network, where different line styles present different sets of subcarriers. In the source phase, A and B are assigned different subcarriers, and they transmit their information to R via their assigned subcarriers simultaneously, and in the relay phase, system subcarriers are assigned to the network coded flow and uncode flow, then the two flows are forwarded by R over their assigned subcarriers simultaneously
