Abstract

Abstract : This paper proposes an effective method to jointly design girth‐4 cycle‐free Quasi‐cyclic (QC) Low‐density parity‐check (LDPC) codes for multi‐relay cooperation in a Rayleigh fading channel, where the joint iterative decoding by Min‐sum algorithm (MSA) based on the introduced joint Tanner graph is also presented at the destination. Theoretical analysis and simulation show that the proposed QC‐LDPC coded cooperation outperforms the randomly coded cooperation under the same conditions.
