Abstract：Channel coding is a very important part of digital communication system. In recent years,LDPC encoding technolo?gy had already become a hot issues of research in coding fields because of its superior characters. The generation of check matrix is the premise for LDPC code,which directly affects the complexity of the encoding and decoding,and which plays a key role for the realization of the algorithm. The paper utilizes algebra constructing methods to construct the check matrix,which is applied to BP de?coding algorithms for LDPC codes constructed. Matlab is adopted to implement the BER simulation of LDPC codes based on the cod?ing-decoding algorithms. Simulation results show that the LDPC codes constructed have a reliable decoding performance.
