Abstract
We investigate a novel coded modulation scheme for physical layer network coding (PLNC) in the two-way relay (TWR) fading channel. Using an adaptive soft demodulator and independent decoding levels, the proposed scheme can eliminate the effect of fading on the TWR channel. To reduce system complexity at the relay, we also give a low-complexity twodemodulator scheme. Based on maximizing the mutual information between received signal and network coded symbol, the adaptive selection of the two demodulators is then optimized. The proposed simplified scheme exhibits advantages in terms of flexibility, complexity and performance.
