DVB-S2-LDPC-BCH

Features

• Irregular parity check matrix
• Layered decoding
• Minimum sum algorithm
• Soft decision decoding
• BCH decoder works on GF (2m) where m=16 or 14 and corrects up to t errors, where t = 8, 10 or 12
• ETSI EN 302 307-1 V1.4.1 (2014-11) compliant

Functional Description

In Digital video broadcasting for digital transmission for satellite applications, a powerful FEC (Forward Error Correction) 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.

Example: Throughput Rates
