Abstract
A method of constructing a base matrix of a permutation matrix, device and medium. The method includes: determining a number Ns of columns corresponding to systematic bits and a number Nrow of rows of the base matrix according to a code rate of the permutation matrix; determining a maximum row weight dc and a total weight range Tweight of the base matrix, wherein the row weight is dc or dc−1; according to Tweight and Nrow, determining a first range R1 of rows with weights of dc−1 and a second range R2 of rows with weights of dc in the base matrix; according to Nrow, Tweight, R1 and R2, filling the systematic bit part in an initial base matrix corresponding to the base matrix to obtain an intermediate base matrix; and performing convergence calculation on it to determine whether it converges, and determining it as the base matrix if it converges.
