| Abstract: | LDPC codes are widely considered as the best error-correction codes nowadays. The worldwide researches on LDPC codes,graph model and iterative decoding have been popular for more than 10 years. This paper provided a brief background and overview of the Low-Density Parity-Check (LDPC) codes and their relevant techniques with original understanding and ideas. It also summarized the state of art and research trend of LDPC codes and presented some important theoretical and application problems of LDPC codes. |
