Problems solved by technology

[0004] If the length of the data to be interleaved is not limited, the triangular interleaver can process any length of data to be interleaved, but the larger the length of the data to be interleaved, the larger the number of rows and columns of the triangular interleaver will be, and the processing complexity and time of deinterleaving will be larger. delay will increase

Embodiment Construction

[0058] This application provides an interleaving method and interleaving equipment to provide a specific solution on how to use a triangular interleaver for interleaving on the basis that the maximum number of bits carried by a triangular interleaver is determined to be 8192 in the 5G standard. Wherein, the method and the device are based on the same inventive concept, and since the principles of the method and the device to solve the problem are similar, the implementation of the device and the method can be referred to each other, and the repetition will not be repeated.

[0059] Embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

[0060] Firstly, the communication system architecture applicable to the embodiment of the present application is introduced.

[0061] figure 2 It shows the structure of a possible communication system to which the interleaving method provided by the embodiment of the present ap...

Abstract

An interleaving method and an interleaving device, being used to provide a specific solution for interleaving bit sequences to be interleaved of which the length is greater than the maximum interleaving dimension determined according to 5G standards. The method is as follows: an interleaving device acquiring a first encoded code block on which rate matching has been performed, the length of the first encoded code block being X, X＞E, E being the maximum interleaving dimension supported by the system, the first encoded code block comprising S sub-code blocks, S being a positive integer greater than 1; the interleaving device interleaving each of the S sub-code blocks, to obtain a second interleaved encoded code block; the interleaving device sending the second interleaved encoded code block.

Description

technical field [0001] The embodiments of the present application relate to the field of communication technologies, and in particular, to an interleaving method and an interleaving device. Background technique [0002] In digital communication, channel coding is often used to improve the reliability of data transmission. In order to further improve the anti-interference performance, some channel coding is added with an interleaving module. On many composite channels where random errors and burst errors occur at the same time, such as shortwave, troposcatter and other channels, when an error often occurs, it will affect the subsequent string of data, causing burst errors to exceed the error correction capabilities of error correction codes. Decrease the error correction capability. If the burst errors are discretized into random errors first, and then the random errors are corrected, the anti-jamming performance of the system will be further improved. In practical applicat...
