Consideration of limitations, which are formed by the input signal, onthe phase error minimization process during carrier frequency tracking system of synchronization of radio technical device of communication ABSTRACTThe successful solution of the problem of maintaining high efficiency of communication and telecommunications systems largely depends on the quality of operation under the influence of various external and internal disturbances and noise of one of the main systems of their composition, namely combined phase synchronization systems. The effectiveness of the combined synchronization system generally depends on various external and internal factors and various restrictions imposed on the process of receiving and demodulating the input signal, the process of monitoring the carrier frequency of the system and minimizing the phase error variance. The presence of such limitations requires their analysis, evaluation and subsequent consideration in the process of synthesis of open communication of the combined synchronization system (СSS). The paper directly considers the issues of increasing the efficiency of the combined synchronization system by taking into account the limitations formed by the influence of a random input signal on the process of minimizing the phase error during the monitoring of the carrier frequency of the specified system. The results of the evaluation of the limitations formed by the influence of the random input signal on the process of minimizing the phase error during the monitoring of the carrier frequency of the СSS of the radio communication device are presented in the paper: in the presence of restrictions on any coordinate of the input signal, the effect of the introduction of an additional link of open communication in the synthesis of СSS is reduced and at some threshold values becomes "0" and the introduction of an additional link does not give the desired effect and becomes impractical; increasing the values of such constraints leads to an increase to the unit ratio of the corresponding functionalities for combined and closed synchronization systems.
