Method and device for transmitting data

摘要

Disclosed is a method for data transmission, comprising: generating the parity check matrix on the basis of the generating sequence corresponded to the preserved row generator; encoding the input data by the generated matrix obtained by said parity check matrix, and obtaining the output data comprising the parity check information. Also provided in the present invention is an apparatus for data transmission. The method and apparatus of the present invention could make the parity check matrix take the minimum storage space.

1. A method for data transmission, comprising:
generating a parity check matrix on a basis of a generating sequence corresponding to a preserved row generator; and encoding input data by the generated matrix obtained by the parity check matrix, and obtaining output data comprising parity check information, wherein the generating the parity check matrix comprising:
determining a number of rows and columns in the parity check matrix on a basis of preset code length, code rate and a dimension of submatrix, and dividing the parity check matrix into arrays in a unit of submatrix;determining elements in a first row of each submatrix on a basis of the generating sequence corresponded to the row generator and a row weight; andobtaining the elements in the other rows of each submatrix, on the basis of the elements in the first row of each submatrix.
