Construction of Rate-Compatible LDPC Codes Utilizing Information Shortening and Parity Puncturing

EURASIP Journal on Wireless Communications and Networking volume 2005, Article number: 692121 (2005) Cite this article

Abstract

This paper proposes a method for constructing rate-compatible low-density parity-check (LDPC) codes. The construction considers the problem of optimizing a family of rate-compatible degree distributions as well as the placement of bipartite graph edges. A hybrid approach that combines information shortening and parity puncturing is proposed. Local graph conditioning techniques for the suppression of error floors are also included in the construction methodology.
