System Model Performance Coupled with DPSK Modulation over Flat Rayleigh Fading Channels
In this paper performance enhancement of the system has been investigated by employing large girth Quasi-Cyclic low-density parity-check (QC-LDPC) codes as forward error correction code, coupled with differential phase shift keying (DPSK) over Rayleigh fading channels. Performance of the system is evaluated by measuring bit error rate (BER) for a given value of . Simulation results at diversity level L=4 have confirmed the robustness of the system with a gain of about 1.5 dB as compared to the results of known differential detection system over Rayleigh Fading Channels at a BER of10^-5 .
