Embodiment Construction

[0036] In order to explain in detail the technical solutions of the cascading compilation method and system of the present application, the following will first explain some related content.

[0037] RS code is a kind of multi-ary BCH (Bose, Ray, Hocquenghem) code with strong error correction ability, which can effectively correct random errors and burst errors. For bursty errors, RS codes can detect continuous bit errors using a relatively small number of symbols. The Qary-LDPC code has the following advantages: first, the error correction performance is better, because the multivariate LDPC code combines multiple bits into a multivariate symbol, which has the potential to eliminate the small and medium rings represented by the bipartite graph of the LDPC code, under iterative decoding Better error correction performance can be obtained; second, the ability to resist burst errors is strong, the binary LDPC code does not have a strong ability to resist burst errors, and the mu...

Abstract

The invention provides a cascade compiling method, a cascade compiling system, a storage medium and computer equipment thereof. An input code stream is coded and decoded through a Q-aryLDPC code and RS code cascade compiling method; therefore, according to the complementary characteristics of the two kinds of compiling codes including a Q-aryLDPC code and an RS code, when the method is applied toa sending end, data blocks after RS coding are interlaced; when the method is applied to a receiving end, data blocks before RS decoding are de-interlaced; by adoption of the Q-aryLDPC code and RS code cascade coding and decoding design, the relatively low error rate performance for signalling transmission is improved; the one-time transmission reliability of signalling in an URLLC application scene can be ensured as much as possible; on the premise that the reliability is ensured, the signalling transmission delay is reduced; and instant messaging requirements of users are satisfied.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular relates to a cascade compiling method, device, storage medium and computer equipment thereof. Background technique [0002] With the rapid development of wireless communication networks, users' demand for wireless data services increases rapidly. In order to support services with high real-time requirements, such as automatic driving, remote control, industrial automation, electric energy, telemedicine, robotics and other application scenarios, Ultra-reliable and low latency coGGunication (URLLC) is the next generation One of the research topics of mobile communication has attracted widespread attention. The reason is that end-to-end communication needs to meet performance requirements such as extremely short delay and low bit error rate. The block error rate index is required to be less than 1e -3 . [0003] In order to ensure that service data can be receive...
