Achieving full diversity in multi-antenna two-way relay networks via symbol-based physical-layer network coding [PDF]
This paper considers physical-layer network coding (PNC) with M-ary phase-shift keying (MPSK) modulation in two-way relay channel (TWRC). A low complexity detection technique, termed symbol-based PNC (SPNC), is proposed for the relay.
