Research output: Contribution to journalArticlepeer-review


A new large girth Quasi-Cyclic low-density parity-check (QC-LDPC) codes have been proposed in this paper. The newly codes are coupled with diversity techniques and are employed as the error correction scheme to cater for some anti-jamming (AJ) competences over Rayleigh fading channels by employing differential phase shift keying (DPSK) modulation scheme. The performance of newly obtained codes is evaluated in term of bit error rate (BER) for a given value of Eb/No. Simulation results have confirmed the robustness of the proposed system at diversity level L=4 with a gain of about 1.5 dB as compared to the results simulated by Tatsunami et al. (2006) at 10-5 BER.
