Influencing the synchronization channel for the digital transmission system
Journal Title: Інформаційно-керуючі системи на залізничному транспорті - Year 2019, Vol 24, Issue 1
Abstract
The purpose of this article is to determine the optimal distribution of energy potential of information and synchronization channels with limitations for peak power for plesiochronous digital transmission systems (DTS) and quasi-optimal choice of potential distribution of synchronous DTS [1, 2], based on the noise immunity criterion. The goal is achieved by systematic physical and mathematical simulation of the synchronization process using the latest results of the theory of radio-electronic measurements [3, 4]. The optimization task is suitable for determining the optimum for the limitations of the peak power of the transmitter or the dynamic range of the first receiver amplifier, as well as in the case of general bandwidth constraints, especially in radio communication satellite systems. The noise immunity in the problem of quasi-optimal choice of energy potentials for synchronous systems with a separate channel of synchronization, depending on its potential and the content band, has the nature of saturation. Therefore, the principle of sufficiency and the optimal solution in the first approximation are used. The expression for measuring precision with automatic synchronization is similar for different types of phase meters or time shifting of the signal fronts. The optimum noise immunity of the transmission system is sensitive to the distribution of energy potential in the transmission system; which depends on the energy potential and the bandwidth of the synchronization channel. Therefore, the creation and operation of systems need to more accurately take into account the impact of such distribution.
