METHOD FOR NOISE-IMMUNE DATA COMPRESSION FOR TRANSMITTING AND STORING INFORMATION Russian patent published in 2025 - IPC G08C19/28 

FIELD: communication technique.

SUBSTANCE: invention relates to telecommunication systems. In the method for noise-immune data compression for transmitting and storing information at the stage of additional encoding of the representation of code words or messages with ternary symbols S_i(T_i), i=0,1,2, generating information phrases including an equal number p thereof, which are represented by formal polynomials F(x)⁽ⁱ⁾, where i is counting set i=1,2,3,…, determining number of information phrases in frame or cycle, comparing modules are selected, for example, m₁(x) = x^{n +1} − 1 and m₂(x) = xⁿ, where n is a number equal to p/2 for p even or p/2+1 – for odd p, then the formal polynomials F(x)⁽ⁱ⁾ successively divided into selected comparison modules, for example, m₁(x) and m₂(x), and obtaining polynomials, which are residues from division b₁⁽ⁱ⁾(x) and b₂⁽ⁱ⁾(x), coefficients of which are used as substitute values of the original code words or messages subjected to compression, wherein a special dividing sign is introduced, which enables to distinguish coefficients of one polynomial-residual b₁⁽ⁱ⁾(x) from the other b₂⁽ⁱ⁾(x), wherein formal description of polynomials-residuals b₁⁽¹⁾(x) and b₂⁽²⁾ (x), operating with coefficients k_n= 0.1.2 for unknown x to corresponding degree, after which they are transferred into sequence of corresponding symbols S_i(T_i) with the same sub-indices i=0,1,2, as a result of which a new generated sequence of symbols is obtained S_i(T_i), wherein in order to distinguish polynomials-residuals from each other b₁⁽ⁱ⁾(x) and b₂⁽ⁱ⁾(x) using division signals (P), which are prohibited in the selected symbol representation system, based on the distinctive signals Ρ, performing division of both code words and messages and coefficients taking values of 0.1 and 2 for polynomials-residuals b₁⁽¹⁾(x) and b₂⁽¹⁾(x), then based on selected coefficients 0.1 and 2 of polynomials-images-residuals b₁⁽ⁱ⁾(x) and b₂⁽ⁱ⁾(x) using adaptive algorithms of the constructive remainder formula, restoring the initial formal polynomials F(x)⁽ⁱ⁾ information phrases in frame or cycle.

EFFECT: high noise-immunity of transmitted and archived information without introducing structural redundancy into transmitted messages and with data compression.
