摘要
Abstract
The Low Density Parity Check Code(LDPC) is a kind of linear block code. The method for construction of parity-check matrix of LDPC is analyzed in view of coding and decoding of LDPC. The coding algorithm of LDPC and its implementation structure are proposed. The belief propagation(BP) algorithm based on soft decision decoding is analyzed,and a simplified decoding method with re- duced computational complexity is also given. The simulation results show the performance comparison between different decoding algo- rithms in Gaussian channel.关键词
