DVB-T2/Lite LDPC Decoder IP

Overview

In Digital video broadcasting for terrestrial broadcasting systems, a powerful FEC sub-system is needed. FEC is based on LDPC (Low-Density Parity Check) codes concatenated with BCH (Bose Chaudhuri Hocquenghem) codes, allowing Quasi Error Free operation close to the Shannon limit.
T2-Lite is intended to allow simpler receiver implementations for very low capacity applications such as mobile broadcasting, although it may also be received by conventional stationary receivers.
