DOCSIS 3.1 - LDPC Decoder Applications

Data Over Cable Service Interface Specification is an international telecommunications standard that permits the addition of high-bandwidth data transfer to an existing cable TV (CATV) system.

The standard describes six LDPC codes, wherof one is taken from DVB-C2. For some codes puncturing and shortening is applied in order to obtain different block sizes and code rates.
