The method of construction of different sets is proposed. The necessary and sufficient conditions for the existence of signals with predetermined correlation and structural properties were formulated. The correlation and structural properties of discrete signals were shown. The mathematical expressions were obtained, and formulated the necessary and sufficient conditions for the existence of the n-level correlation function significantly simplify of the procedures for synthesizing signals with the given correlation properties. Solution the problem of increasing noise immunity, imitative stability and secrecy was associated with the use these sets of signals, which satisfyi the requirements. Each signal of this ensemble is easy distinguish from a shifted copy in time, each of the signals of this ensemble is easily different from any other signal of this set. The developed algorithm of construction of different sets allows to synthesize and investigate the statistical characteristics of auto - and inter - correlation properties of discrete signal systems. Synthesis and investigation of the properties of discrete signal systems with n-level correlation function can be carried out within or only non-inverse and inverse isomorphic, or arbitrary combination of those and other transformations. In this case, the choice of any arbitrary duration of the signal is provided.Downloads
