Good high-rate π-rotation LDPC codes based on novel puncturing techniques
Rich Echard, Shih-Chun Chang · 2010
In this paper we introduce puncturing techniques to produce high-rate π-rotation low-density parity-check (LDPC) codes. The techniques rely on symmetry considerations to maintain simple description and to achieve excellent performance. We also extend the bounds on the minimum d2for the high-rate codes.
