Low-density parity-check (LDPC) codes are a class of linear block code capable of performing extremely close to the capacity of a channel as defined by Shannon. The purpose of this chapter is to provide an overview of the basic ideas, as well as the main results, in the field of LDPC code construction. No attempt could possibly be made ...
