英文摘要	Based on superposition coding and physical-layer network coding technologies, a new joint superposition coding and physical-layer network coding (JPNSC) relaying strategy is proposed. The strategy system model is a linear four-node wireless system aiming to realize the two-way information exchanges of two pairs through the cooperation of the intermediate two nodes. Through the analysis of two-way relaying transmission strategy based on superposition coding using four time slots and the corresponding systematic throughput, a new two-way relaying strategy based on joint superposition coding and physical-layer network coding is proposed which only needs three time slots to complete the whole transmission process. With the mathematic derivation and numerical analysis, the results show that it not only increases the spectral efficiency by 25%, but also improves the systematic throughput.
