概述和功能介绍

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.

功能描述

• Irregular parity check matrix
• Layered decoding
• Minimum sum algorithm
• Soft decision decoding
• BCH decoder corrects up to t errors where t = 10 or 12
• ETSI EN 755 V1.4.1 compliant

 Deliverables

• Synthesizable Verilog (ASIC)
• System Model (Matlab)
• Verilog Test Benches
• Documentation
