Construction Method Of Ldpc Codes Used For Satellite Interactive System

This paper firstly points out the disadvantage and advantage of Turbo Codes and LDPC codes which are used in satellite interactive communication system, then it introduces the common construction method. Subsequently, this paper putts forward a new construction method of a type of LDPC codes which is fit for satellite interactive communication system. Finally, error correction performance of LDPC Codes which are constructed using this method and Turbo codes is simulated comparison.
