Symbol rate, transmission rate and forward error correction (FEC).

WebThe DVB-S2 standard has been specified around three key concepts: best transmission performance, total flexibility and reasonable receiver complexity. To achieve the best performance-complexity trade-off with an appreciable capacity gain over DVB-S, DVB-S2 benefits from more recent developments in channel coding and modulation. WebFor example, in the case of QPSK modulation and AWGN channel, the BER as function of the Eb/N0 is given by: = ⁡ (/). People usually plot the BER curves to describe the performance of a digital communication system.
