Information symbol encoding method for use in coded image transmission application, involves completing words corresponding to redundancy symbol such that other formed words is orthogonal to one matrix, and forming code word

摘要

The method involves selecting a tuple and a tuple of diagonal square matrix of predetermined dimension on Galois field. Information symbols are placed successively in words of predetermined length, and other words of predetermined length are formed. The former words are completed corresponding to redundancy symbols such that the latter word is orthogonal to another matrix and a code word is formed. Independent claims are also included for the following: (a) a method for decoding of received data resulting from transmission of coded symbols (b) a method for communication of information symbols (c) a device for encoding information symbols according to code defined on Galois field (d) a device for decoding of received words resulting from transmission of coded words (e) an apparatus for transmission of information data (f) an apparatus for reception of data (g) a data storing component (h) a computer program comprising instructions allowing data processing device to implement encoding method and/or decoding method and/or communication method.
