In this work we determine the achievable rate in a multi-source relaying system with Gaussian phase-fading channels. In our system, M sources simultaneously transmit their messages to a common destination in M separate frequency bands with the help of a single relay (an M − 1 − 1 system). The achievable rates of both a separate processing scheme at the relay, and a network coding scheme at the relay,...
We investigate LDPC code design for a multi-source single-relay system, with uniform phase-fading Gaussian channels. We specifically consider the asymmetric channels for multiple sources, where the channel condition for each source in the system is different. We focus on LDPC code design when network coding (NC) at the relay is utilized. For the asymmetric sources, we firstly introduce a binary field...
