Problems solved by technology

The division of code groups before encoding and the combination of code segments after decoding require a lot of overhead time, and the transition time of encoding and decoding is too long to be high-speed and real-time
[0011] It can be seen that using existing codec solutions to solve the problem of reliable data storage or transmission, it is difficult to balance codec efficiency and error tolerance

Embodiment Construction

[0051] The present invention proposes a coding method for reliable data storage and transmission, which includes the following steps for source data processing,

[0052] (1.1) Carry out error control coding, construct launch vector A;

[0053] (1.2) Carry out cross-permutation encoding according to the transmission vector A, and the cross-permutation coding process is to get m transmission vectors A 0 , A 1 ,...A m-1 , launch vector A 0 , A 1 ,...A m-1 Each of them has n components, forming an m-row×n-column storage array, storing the storage array into n memories in row order, or concatenating in column order to form a baseband signal vector M with a length of mn A .

[0054] The key improvement of the present invention is to use error control and cross-permutation combined coding to achieve double error control effects in a simple way, and because the error control effect is strong, there is no need to increase the length of the supervisory code and the corresponding c...

Abstract

A coding and decoding method of source data includes carrying out error control coding to structure emission vector A then carrying out intercrossing arrangement coding according to emission vector A; carrying out intercrossing arrangement decoding as per intercrossing arrangement reverse transform rule then carrying out error correction decoding on receiving vector B obtained by intercrossing arrangement decoding. The relevant data storage system and data transmission system are also disclosed.

Description

technical field [0001] The invention belongs to the field of electronic information, and in particular relates to encoding and decoding methods and applications for reliable storage or transmission of data. Background technique [0002] The processing of data is the basic content of the field of electronic information, and ensuring data reliability is an important topic in this field. Among them, there are two most difficult situations to deal with: the security of large-capacity data storage in a weak radiation environment and strong interference Reliable transmission of data in poor channel environments. [0003] Reliable storage of large-capacity data in a weak radiation environment: [0004] In space, there are cosmic rays and various high-energy particles, including high-energy protons, neutrons, alpha particles, and heavy ions. This type of particle has high energy, very much like a tiny high-speed bullet. This type of particle impacts the chip. If it passes through ...
