Description
This course is intended for engineers and students who would like to get a background in the basic concepts in forward error correction techniques but would like to take a deeper outlook into the modern concepts and technologies that are employed in today’s high-speed optical communication systems. The course is intended to give participants insights on the selection of FEC schemes for different applications and the understanding of LDPC-based FEC schemes, which form one of the most popular coding schemes in optical communications these days.
Some of the topics covered in the course are:
- Recapitulation of basic concepts of forward error correction (FEC)
- Hard-decision decoding versus soft-decision decoding
- Basic concepts, potential gains and possible limitations
- Guidelines for decoding method selection depending on application
- Applying forward error correction in optical transmission experiments
- Performance characterization using information theoretic methods
- Performance evaluation using real decoders
- In-depth treatment of modern FEC schemes
- Product codes and staircase codes for hard-decision decoding
- Concatenated coding schemes
- LDPC codes for soft- and hard-decision decoding
- Common designs of parity-check matrices, e.g., Quasi-Cyclic (QC) codes
- Decoding LDPC codes – algorithms for soft-decision and hard-decision decoding
- Decoding LDPC codes – hardware implementation aspects
- Simulation of LDPC codes on FPGAs for error floor analysis
