Improving FEC layer frame for DVB-S2 link system based on 5G NR polar coding

Within the scope of this investigation, MATLAB simulation code for digital video broadcasting–for satellite–second generation (DVB-S2) has been constructed. Forward error correction (FEC) rates as 3/5, 2/3, and 3/4 across additive white Gaussian noise (AWGN) Rayleigh fading channels are used to evaluate system's performance, mainly while working on quadrature phase-shift keying (QPSK), 8-ary (8PSK), 16-ary amplitude (16APSK), 32-ary (32APSK) official modulation types. The redesign achieved investigate high performance reliability based a cascade new radio (NR) fifth (5G) Polar coding with low-density parity-check (LDPC). Some signal-to-noise ratio (SNR) levels were changed when evaluated in contrast conventional model. It determined that five iterations LDPC decoder performed. In comparison traditional proposed design's accomplished highest possible value reducing bit rate (BER) investigated better-transmitted power gain most testing cases.
