Abstract

The embodiment of the invention provides a coding method, a decoding method, coding equipment and decoding equipment. The coding method comprises the steps as follows: a sending terminal acquires the length of data after polar coding corresponding to the data to be coded; the sending end divides the data to be coded into at least one segment of coded blocks according to the length of the coded data and a preset threshold; and the sending end performs polar coding on each coded block, and transmits the coded data to the a receiving end. According to the methods and the equipment provided by the embodiment of the invention, the problem that loss of data transmission performance caused by too much segmenting is avoided.

Description

technical field [0001] The present invention relates to the field of technical communication technology, in particular to an encoding and decoding method and equipment. Background technique [0002] In the Turbo coding process of the Long Term Evolution (LTE) system, once the transport block (Transport Block, TB) length exceeds the maximum input bit length of the Turbo coder (ie, the maximum interleaver size of the Turbo code), it is necessary to The TB block is divided into several shorter code blocks, so that the length of each code block can meet the size of the largest interleaver, thereby completing the encoding process of each code block. Wherein, a cyclic redundancy check (Cyclic Redundancy Check, CRC) and padding bits are added to the code block. During code block segmentation, all padding bits are always added at the beginning of the first code block. [0003] Due to the limitation of the interleaver of the Turbo code, a large number of Turbo codes have to be divi...
