Abstract
Since Quasi-Cyclic LDPC (QC-LDPC) codes have many advantages for fast encoding, they are adopted in channel coding of the Chinese Digital Terrestrial Television Broadcasting (DTTB) Standard. The construction of QC-LDPC codes in Chinese DTTB standard, which is based on the structure of RS codes with two information symbols, is described. Also, three fast encoding circuits are presented, which encode in serial, parallel and partial parallel, respectively. They have speeds and complexities that differ with each other. According to the requirements of the system, one of them can be chosen carefully.
