Abstract:

The algorithm of threshold calculation for low-density parity-check (LDPC) codes is investigated. The design steps of degreesequence which has higher threshold and the process of constrained problem are discussed in detail. A method of degreesequence design for LDPC on particle swarm optimization (PSO) is presented. The analysis and comparison of estimation result and some capacityapproaching degree-sequences are also given.
