3. Advances in Detection and Error correction For coherent Optical Communications: Regular, Irregular, and Spatially Coupled LDPC Code Designs It also gives an introduction to LDPC codes and shows how irregular LDPC codes can be designed to be well-adapted to differential coding. The chapter ......
In the remainder of this chapter, we will give an introduction to LDPC codes and present decoding and encoding circuits together with code classes suitable for high-speed operations at throughputs of 100 Gbps and beyond. Finally, we will show how different soft-decision FEC codes can be ...
In one embodiment, a de-interleaver receives soft-output values corresponding to bits of an LDPC-encoded codeword. The de-interleaver has scratch pad memory that provides sets of th

This paper describes the implementation of a general and embedded decoder for the evaluation of unstructured low-density parity-check (LDPC) codes over additive-white Gaussian noise (AWGN) channels. The decoder, which has a serial architecture and moderate throughput, is a peripheral connected to th...
Belief-propagation decoding for low-density parity-check (LDPC) codes only performs well if the decoder does not get stuck during information exchange between variable and check nodes, i.e. performs above a certain threshold. As the binary erasure channel and the binary symmetric channel are both...
LDPCWBFerror floorreliability-saturation strategyIn weighted bit-flipping-based algorithms for low-density parity-check (LDPC) codes, due to the existence of overconfident incorrectly received bits, the metric values of the corresponding bits will always be wrong in the decoding process. Since these ...
