A Deterministic Construction for Jointly Designed Quasicyclic LDPC Coded-Relay Cooperation

Muhammad Asif, Wuyang Zhou, Qingping Yu, Xingwang Li, Nauman Ali Khan
2019 Wireless Communications and Mobile Computing  
Firstly, a design-theoretic construction of QC-LDPC codes based on a combinatoric design approach known as optical orthogonal codes (OOC) is presented.  ...  This correspondence presents a jointly designed quasicyclic (QC) low-density parity-check (LDPC) coded-relay cooperation with joint-iterative decoding in the destination node.  ...  However, QC-LDPC-coded cooperation provides more flexibility for code length and rate selection, and encoding complexity is linear in nature.  ...
