The DVB-S2 LDPC-BCH block is a powerful FEC
(Forward Error Correction) subsystem for Digital
Video Broadcasting via Satellite.
DVB-S2 LDPC BCH Decoder and Encoder
Overview
Key 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
- Long and short frame lengths
- No error floor to QEF in Standard
- Easy to integrate within receiver
- All code rates and modulation orders
Benefits
