LDPC codes for LTE-Advanced and research on encoding and decoding algorithm
LDPC码在LTE-Advanced中的应用及编译码算法研究

The paper introduced the basal construct rule of LDPC Code check matrix in LTE-Advanced system, and found the expanded method which was compatible with LTE, then this paper put forward two optimize encoding algorithm. Simulation by MATLAB tool, modified min sum-product decoding algorithm was proposed. The simulation result shows that the LDPC decoder has such advantages as high efficiency to meet the demand of precision digital signals transmission. Analyzing and contrasting the improved algorithm to find the optimum modified value. This paper provided an effective coding and decoding algorithm scheme for hardware design in LTE-Advanced, having some practical value.
