A METHOD OF DATA ENCODING/DECODING USING VARIABLE LOW DENSITY PARITY CHECK CODES

Abstract

This paper presents a coding method that dynamically changes the low density parity check (LDPC) code parameters in accordance with communication channel quality. The apparatus for parity check matrices generation, storage, and dynamic change are proposed. Some simulation results for different code characteristics and performance are provided that prove the effectiveness of proposed method.
