LDPC coding simulation
4.0
LDPC code is low density parity check code (LDPC). It is a kind of linear block codes with sparse check matrix proposed by Dr. Robert G. Gallager in 1963. It not only has good performance of approaching Shannon limit, but also has low decoding complexity, Flexible structure is a research hotspot in the field of channel coding in recent years. It has been widely used in deep space communication, optical fiber communication, satellite digital video and audio broadcasting. LDPC code has become a strong competitor of the fourth generation communication system (4G), and the coding scheme based on LDPC code has been adopted by the next generation satellite digital video broadcasting standard DVB-S2.
