Quasi-cyclic extension based on PEG algorithm for construction of LDPC codes

Quasi-cyclic extension based on PEG algorithm for construction of LDPC codes

Several important relations between the cycle structure on the Tanner graph and the parity-check matrix H of LDPC codes were proved.A new algorithm for constructing LDPC codes was proposed that introduced quasi-cyclic ex-tension method to PEG algorithm.After a basic matrix was constructed with PEG a...
