Abstract
Since the introduction of coherent transponders, forward error correction based on soft decision is now established in optical communication. In this paper, we give a tutorial-style introduction of one class of commonly used codes, namely low-density parity-check (LDPC) codes. Also we discuss new developments such as convolutional LDPC codes and show how they can be employed as potential candidates for future optical communication systems.Keywords
