Encoding method, encoding device and encoder

Abstract

The invention provides an encoding method, an encoding device and an encoder, and the method comprises the steps: segmenting a data block to obtain a plurality of code blocks, the code length of the code blocks being smaller than a preset code length; filling the plurality of code blocks to obtain a plurality of code blocks to be coded, the code length of the code blocks to be coded being equal to a predetermined code length; lDPC coding is performed on the to-be-coded code block to obtain a plurality of coded code blocks, the code rate of the coded code blocks is equal to a target code rate, the target code rate is greater than or equal to a minimum code rate, and the minimum code rate is equal to the ratio of the predetermined code length to the maximum code length of the coded code blocks. Compared with the prior art in which the code length of the coding code block obtained by coding calculation is equal to the maximum code length and then rate matching is performed, the method reduces the calculation amount of coding calculation, reduces the coding time delay and power consumption, and solves the problem of long time delay of a coding method in the prior art.

Description

technical field [0001] The present application relates to the field of wireless communication, and in particular, relates to an encoding method, an encoding device, a computer-readable storage medium, a processor, and an encoder. Background technique [0002] With the development of wireless communication, people's demand for large-capacity, low-latency, high-reliability, high-speed, high-connection, and high-energy-efficiency communications will increase significantly. Application scenarios include not only wide-area coverage, but also dense hotspots, machine Inter-communication, Internet of Vehicles, large-scale open-air gatherings, subways, etc. These applications can be roughly classified into three scenarios: enhanced mobile broadband eMBB, low-latency and highly reliable URLLC, and massive Internet of Things mMTC. Channel coding is the most basic technology of the physical layer, and will play a direct and indirect role in various performance indicators of the 5G syst...
