In this chapter, low-density parity-check (LDPC) codes, a class of powerful iteratively decodable error correcting codes, are introduced. The chapter first reviews some basic concepts and results in information theory such as Shannon’s channel capacity and channel coding theorem. It then overviews the Flash memory channel model. Finally, it addresses LDPC codes describing both their structure and efficient implementation, and their decoding algorithms. Simulation results are also provided.

Abstract
In this chapter, low-density parity-check (LDPC) codes, a class of powerful iteratively decodable error correcting codes, are introduced. The chapter first reviews some basic concepts and results in information theory such as Shannon’s channel capacity and channel coding theorem. It then overviews the Flash memory channel model. Finally, it addresses LDPC codes describing both their structure and efficient implementation, and their decoding algorithms. Simulation results are also provided.File in questo prodotto:
