| Popis: | Low Density Parity Check (LDPC) and Bose-Chaudhuri-Hochquenghem (BCH) are channel coding that have been recently developed associated with QPSK, 8PSK, 16APSK, and 32APSK modulations for the system to work properly on the nonlinear satellite channel. The likelihood of either system bit error or block error probability is one of the most commonly used features in modern communication systems. This paper initially introduces the main components used to build a video broadcast digital system model — satellite second generation (DVB-S2). The next part of this work implement's MATLAB Simulink model to use low-density parity check code (LDPC) since it is a key element in this system. Next this paper examines the extent of performance of this application at small set of ModCods with (QPSK) at different values of (E S / N o ) of energy per symbol noise ratio PSD's. Finally the relationship between (BER) and (ES / No) is presented as the output values obtained by this order. |
