Low-Density Parity-Check Codes with Cyclic Structure of Macroblocks
Abstract
Introduction: Modern infocommunication systems require a very high rate of data transmission with high reliability, i.e. low probability of an error. To fight the distortions in a communication channel, error-correcting codes are traditionally used. Low-density parity-check codes are one of the most powerful and effective modern error-correcting techniques. However, to attain a high rate of the transmission, it is not enough to use codes which only correct errors and have simple encoding/decoding procedures. The very construction of the codes should facilitate a more effective implementation, including the hardware level. Purpose: The goal is to construct effective low-density parity-check codes whose structure would allow you to optimize the existing decoder architectures. Results: A modification of low-density parity-check code has been proposed, based on Reed-Solomon codes. It has a cyclic structure of macroblocks. It is shown how this structure can be used to optimize the architecture of a partially parallel decoder based on a layered belief propagation algorithm. Practical relevance: The proposed code construction and decoder architecture allow you to achieve low error probabilities in high-rate data communication systems (e.g. optical wired lines).Published
