  • This paper proposes an efficient interference mitigation and joint decoding scheme for uplink LDPC-coded relay cooperation over a Rayleigh fading channel, where a concatenation ofMinimum-mean-squared error linear detectors (MMSE) and BP-based joint iterative decoding based on the introduced treble-layer Tanner graph are effectively designed t ofilter and decode the corrupted received sequence at a base station. It is demonstrated by theoretical analysis and numerical simulations that the proposed design can well combine the gains from coding and diversity, which consequently leads to a significant performance improvement over the conventional cooperation system under the same conditions.
