Abstract

The article presents an original approach to modeling the quality of delivery of reference time and frequency signals using the spectral correlation theory of random processes. This and similar problems arise in solving modern design (synthesis, optimization) problems of time-frequency support systems for information infrastructure facilities, including those using alternative sources of reference signals. Implementation of this approach will form the foundation for developing new core elements of a theory for constructing a Unified Time- Frequency Support System for the National Information Infrastructure. The core of such a theory is proposed to be an analytical description of the dependence of time and frequency signal quality on the causes and characteristics of their fluctuations. The importance of these patterns stems from the fact that the potential range of their distribution depends on the discount rate of time and frequency signal quality. This, in turn, determines the key topological characteristics and cost of the time-frequency support system for the information infrastructure.
