QC-IRA-d Codes Based on Circulant Permutation Matrices

摘要

This paper presents a new kind of quasi-cyclic irregular repeat accumulate (IRA) codes based on circulant permutation matrices called QC-IRA-d codes. The presented QC-IRA-d codes have lower encoding complexity than traditional IRA codes and can be decoded in a partially parallel decoder like QC-LDPC codes. Simulation results show that QC-IRA-d codes have good error-correcting performance.
