Abstract(in English) | Physical-layer network coding~(PNC) enables bi-directional wireless communications with low density parity check~(LDPC) coded orthogonal frequency division multiplexing~(OFDM) to achieve the frame exchange with half of time slots required conventional wireless relaying.In synchronous PNC, the receive amplitude and phase simultaneously transmitted from both the end nodes are synchronized at the relay node with the permissible subcarrier power.In this manuscript, we propose a compensation scheme of log-likelihood rate~(LLR) at the relay node to estimate the precoding weight error due to echo channel estimation and evaluate its performances in terms of frame error rate~(FER).Furthermore, we show the throughputs of conventional relaying, XOR network coding~(XOR-NC), and PNC for given two-way relay channels. |
