Abstract
A degree distribution mapping method of parity check matrix in irregular QC-LDPC based FSO communication is proposed. Before channel coding, use the mapping method to select the appropriate distribution of the parity check matrix corresponding to atmospheric channel estimation feedback. BER performance of the optimal distribution of the parity check matrix in different turbulence intensity has been made. Compared to old coding schemes without optimizing degree distribution, the new one have greatly improved the transmission performance.
