Konovalov O. Development and research of methods for controlling communication channels characteristics

Object of investigation is parameters and characteristics of communication channels. Subject of investigation is methods for controlling communication channels characteristics. As a result of a study the method of combining cross-correlation measurement of communication channels characteristics obtained further development; new modification of the method is proposed on the basis of cepstral regularized decision of the basic equation for measurement and recommendations are given as to the choice of the decision method; correlation is established between time, frequency and power parameters of signals during the combined cross-correlation measurement which enable to obtain the criterion of feasibility of the process of combined cross-correlation real-time measurements; recommendations are given as to the choice of parameters of noise-like signals for measurement; the structural synthesis of characteristic control devices that realize different modifications of the combined cross-correlation method is made; mathematical model of the combined cross-correlation method is developed as software package; in the process of modeling an accuracy of communication channel characteristics measurement for different modifications of the combined cross-correlation measurements is investigated. An application domain is the system of telecommunications
