“…The research results in form of graphs which describe transient process for the value of SNR that corresponds to error probability p0=10 -3 ( Fig. 6) and assessed dependences of transient process duration in a system in case of deviation of current dispersion σ 2 current of synchronization error on its value in stationary mode σ 2 stationary, testify that in case of narrowing band in synchronization system, what means reducing monitoring error, the transient process time gets increased ( Fig. 4).…”

“…The main purpose of the presented results is to supplement and summarize information on the specifics and nature of synchronization conditions in the means of determining the factors that qualitatively influence the factors contributing to the noise immunity of modern information processing systems [2,3]. The coherent and quasicoherent methods for signal receiving require phase locked loop (PLL) frequency as obligate component which forms the reference signal from the received oscillation [4]- [6].…”

“…To receive discrete information a system needs clock, word and frame synchronization. The important task of synchronization, which is to form reference oscillation at the receiving side of wireless connection, in most of the cases, becomes complicated due to influence of noise, which distorts the received signal, and in some cases due to random character of the signal itself [2].…”

This paper represents analysis of principles providing maximally reliable delay estimation of signal synchronization devices in telecommunication. Clock synchronization schemes on the base of stochastic models, graph-analytic interpretation, analytical functional description and their parameters selection in case of real complex hindrance are analyzed. Dependences between dispersion of maximally reliable estimation of synchronization devices and signal to noise ratio (SNR) are represented. Analytical expressions and dependences are obtained for deviation of synchronization error with respect to SNR at the output of discriminator. Diagrams of state are formed for assessment of digital synchronization device in case of error state. Calculated error of numerical solution of the equation of a stationary grid method. We obtain the schedule of the distribution of the probability density synchronization errors for different values of the normalized time. The functions performed by the symbolic synchronization circle, features of the construction of the timing error detector (TED) are analyzed. The Gardner, Early-Late, Mueller & Muller TED, their error and the S-curve equation are investigated. The dependence of the relative timing error on the SNR is obtained. The article examines the effects of interpolation and decimation conditions in the forming filters of digital communication systems.

“…Progress in modern telecommunication systems is connected with using complicated signal and code structures to form information signals [1][2][3][4][5]. Thus both phase locked loop (PLL), which recovers signal carrier frequency and clock synchronization devices (CSD) are needed to be included to the receiving part.…”

In this paper represents research improving effectiveness of signal processing in telecommunication devices especially for its part, which relates to providing its noise resistance in conditions of noise and interference. This objective has been achieved through development of methods and means for optimization of filtering devices and semigraphical interpretation of clock synchronization systems in telecommunications with frequency shift keying on the base of stochastic models what determines relevance of the subject. Separately, in an article considered the urgent task is using of modified synchronization methods based on the interference influence of adjacent symbols on the phase criterion tract, in particular the use of the modified synchronization scheme, in order to get a formalized outlook representation of the synchronization schemas based on the polyphase structures with using a bank of filters, that allows to improve the characteristics of digital telecommunication channels. This work is devoted to the examination and modeling of these ways. The proposed ideas and results for the construction of synchronization systems can be used in modern means of telecommunication.
