Abstract
LDPC codes not only play an important role in ensuring the security of communication, but also show a great prospect in the relatively poor channel environment.Therefore, there is reason to believe that further research on LDPC codes will help to improve the quality of communication.In this paper, the FPGA implementation of LDPC shortcodes with random structure is focused on, and the logarithm domain decoding algorithm with higher complexity is adopted to obtain better decoding performance.And in the process of realization, the state machine is used to control the decoded modules, and the corresponding sequential waveform of the decoding unit are obtained by Modelsim software.关键词
