Enactment of LDPC Code Over DVB-S2 Link System for BER Analysis Using MATLAB

Abstract

In this paper, Digital Video Broadcast—Satellite Second Generation (DVB-S2) Simulink model on MATLAB is evaluated. To analyze the performance especially while working on 8PSK modulation, FEC rates as 3/4, 3/5, and 9/10 along with low-density parity-check (LDPC) codes chained with Bose–Chaudhuri–Hochquenghem (BCH) codes for effective transmission. To examine this application performance, several entries of energy per symbol noise ratio (Es/No) were changed for model behavior detection. LDPC decoder iteration relationship analysis and LDPC bit error rate analysis have been carried out. After examining this has been evaluated at which FEC rate this model response finest.
