Lower Computation and Storage Complexity of QC-LDPC Codes in Rayleigh Fading Channel

Abid Yahya, Othman Sidek, M. F. M. Salleh and Farid Ghani

Abstract—This paper presents the construction of large girth Quasi-Cyclic low density parity check (QC-LDPC) codes and anew multicarrier frequency hopping spread spectrum(MCFH-SS) system. The performance of newly obtained codes is evaluated by comparing with Reed Solomon (RS) codes. The computer simulation results show that the two girth-twelve QC-LDPC codes significantly outperform conventional RS codes with a gain of 2.1 dB at
