Low Density Parity Check(LDPC) code itself has a good performance and the application of LDPC in the communication field is extensive. LDPC codes have the characteristics of low bit error rate, easy adjustment, low decoding complexity and excellent decoding performance. LDPC is considered to be the "best performance" in the field of coding and decoding [1] . In this paper, we mainly introduce the theory of LDPC codes. And the use of the method of the LDPC code to do a further explanation.
more » ... l simple decoding schemes of LDPC are studied. Finally, using the method of function approximation to replace the confidence function to improve the BP LLR algorithm, and simulation experiments are carried out.
