Problems solved by technology

[0003] In the application of traditional error correction codes, the change of packet error probability in the channel link is rarely considered. The use of fixed redundant parity bits in the encoding leads to the reduction of bandwidth efficiency, which cannot meet the variable QOS in different applications ( quality of service) requirements

Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0024] The present invention provides a kind of self-adaptive Reed-Solomon (Reed-Solomon) decoder structure, this structure improves traditional decoder structure, adds two stages of FIFO storage parameters and data respectively in different positions, avoids It solves the problem of data conflicts when dealing with data blocks of different lengths, and ensures the integrity of the interval information of the output decoded data blocks. At the same time, it optimizes the functions of each module to make it more suitable for adaptive decoding.

[0025] This adaptive Reed-Solomon decoder structure provided by the present invention is improved on the basis of the traditional adaptive Reed-Solomon decoder structure, and the fu...

Abstract

The invention relates to the field of applied technology of Reed-Solomon error correcting code, and discloses a self-adapting Reed-Solomon encoder which at least comprises an adjoint polynomial computing module, a key equation resolving module, a primary FIFO and an error computing module. Based on the structure of the traditional self-adapting Reed-Solomon encoder, the encoder of the invention is improved, the function division of work and the layout of the submodules are optimized, so that processing delay is minimized when the self-adapting function is realized. The self-adapting Reed-Solomon encoder can decode a coded data block of truncated code which has length change in the same GF region of Reed-Solomon code application in a self-adapting way, and not only can process the single coded data block, but also the continuous coded data block; in addition, the gap of the data block which is output by decoding is consistent with that of the data block which is input, thus ensuring the integrity of the information of data block gap.

Description

technical field [0001] The invention relates to the technical field of application of Reed-Solomon (Reed-Solomon) error correction codes, in particular to an adaptive Reed-Solomon decoder using variable-length truncated codes. Background technique [0002] Reed-Solomon (Reed-Solomon, RS) code is a multi-ary cyclic block code defined in the GF(2m) domain, it has the ability to correct burst errors and random errors at the same time, so it is widely used in data communication It is an important means to improve the reliability of data transmission and storage in the error control of data storage system. It is therefore widely used in many high-speed applications, such as wireless broadband communications, HDTV, ATM, and optical fiber communications. [0003] In the application of traditional error correction codes, the change of packet error probability in the channel link is rarely considered. The use of fixed redundant parity bits in the encoding leads to the reduction of b...
