The DVB-S2X LDPC Decoder is a powerful FEC core decoder for Digital Video Broadcasting via Satellite. It implements extensions to the DVB-S2 design for better performance and efficiency as well as
robust service availability.
DVB-S2X LDPC BCH Decoder and Encoder
Overview
Key Features
- Irregular parity check matrix
