DVB-S2X-LDPC Decoder IP
Overview
In Digital video broadcasting for digital transmission for satellite applications, 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.
Key Features
- Irregular parity check matrix coding
- Layered Decoding
- Minimum sum algorithm
- Soft decision decoding
- ETSI EN 302 307-2 V1.1.1 compliant
- Long, medium, and short codeword lengths are supported (16200, 32400 and 64800 bits)
- All code rates of EN 302 307-2 V1.1.1 standard are supported
Benefits
- Improved performance
- Improved efficiency w.r.t. Shannon's limit
- Finer gradation of code rate and SNR
- Very high data rate
- Maximum service availability at highest efficiency
- Enables cross layer optimization
