Optimization of the method for the synthesis of discrete folding signals in the most common bag-box-and-bag systems

Abstract

Among the main areas of improvement of the performance indicators of information and communication systems (ICS), in particular, noise immunity, secrecy, and information security, it is possible to identify the areas associated with the use of phase-manipulated broadband signals (FM SHPS). Numerous ICS applications point to the importance of periodic autocorrelation properties of the signals used: continuous-beam systems with continuous radiation, pilot channel and channel of synchronization in digital data systems, radar and sonar systems, and others. In addition, a good periodic AKF signal indicates the ability to select signals with good aperiodic ACF. The minimization of the level of the side petals of the AKF is of greatest importance when designing a signal for such applications as measuring the lag time, time resolution, etc. In this paper, the problem of optimizing the synthesis of nonlinear discrete sequences, which have improved ensemble, structural and autocorrelation properties, is formulated and solved. The use of nonlinear discrete signals, which are formed on the basis of such sequences, will provide the necessary values of impedance protection, information and structural secrecy of the operation of the ICS.
