On Non-Binary Constellations for Channel-Coded Physical-Layer Network Coding

The authors investigate channel-coded physical-layer network coding in a two-way relaying scenario, where the end nodes A and B choose their symbols, SA and SB, from a small non-binary field, F, and adopt a non-binary PSK modulation. The relay then directly decodes the network-coded combination aSA + bSB over F from the noisy received superimposed channel-encoded packets. The advantage of working over non-binary fields is that it offers the opportunity to decode according to multiple decoding coefficients (a, b).
