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

<p/> <p>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 inform...
