The Algorithm of Nonlinear Data Coding and Decoding by Fixed Point Transformations for Secured Mobile Digital Communication Systems

The article discusses the method of coding and decoding of binary information stream by the methods of nonlinear dynamics in a finite Galois Field, each state in which is determined by a known value. The proposed algorithm is defined for values with a sign and provides effective signal coding and decoding for digital communication systems. Algorithms and the results of numerical modeling are given. The fundamental possibility of self-healing the decoding ability of the signal processing device under the conditions of interference is shown.
