BCH Encoding and Decoding Algorithm and Digital Demodulation Technology based on DVB-S2 Standard
Shikang Nie, Yifeng He, Guangting Li, Chenchen Lin · 2022
By comparing the research status of BCH codec based on DVB-S2 standard at home and abroad, it is pointed out that it is important to realize high-speed and small size BCH parallel codec circuit to improve system performance. Finally, two kinds of data synchronization techniques using unified time reference between receiver and transmitter are introduced, which are symbol synchronization and frame synchronization.
