Problems solved by technology

[0005] However, when using multiple different expansion factors to expand the same base matrix, it is usually difficult to ensure that each check matrix formed has good ring length characteristics, for example, the number of 4 rings is small
Under certain expansion factors, the base matrix generated by expanding the base matrix will have a relatively high error floor, which will affect the reliability of data transmission using LDPC with the corresponding code length of the expansion factor

Abstract

The invention provides a data transmission method and wireless communication equipment, wherein the method comprises the steps of: obtaining a first basis matrix of an LDPC code; and coding an information sequence according to the first basis matrix, an extension factor z<f> and a freedom factor r<f>, so that a first coded sequence is obtained. By adoption of the method and the equipment providedin the invention, the freedom factor r<f> is introduced as one freedom degree; when a second basis matrix corresponding to the extension factor z<f> is generated, completely different second basis matrix structural distributions are obtained; and thus, the problem that the generated second basis matrix has a relatively high error floor under the extension factor z<f> can be lightened.
