Study of equivalent point-to-point transmission model for coded relay cooperations

Abstract

LDPC-coded relay cooperation and its joint iterative decoding based on the bi-layer Tanner graph were investigated.The coded relay cooperation becomed an equivalent and relatively simple point-to-point transmission model by introducing the notation of average arithmetic/geometr SNR for the receiver in the destination,which could be employed to perform the further study on more complex coded relay cooperations.Both LDPC-coded relay cooperation and its equivalent point-to-point model have almost the same performance by theoretical analysis and ical simulation,which proves the validity of the introduced equivalent model and the joint iterative decoding based on bi-layer Tanner graph.
