Abstract
Rate-compatible low-density parity-check (LDPC) codes obtained from the class of array LDPC codes are presented. Our approach builds on the deterministic array LDPC code construction and allows efficient encodability across all codes in a rate-compatible family. Furthermore, the use of permutation matrices as building blocks of the parity-check matrix permits efficient decoder implementation. The suitability of rate-compatible array (RCA) LDPC codes for various applications is examined.
