Mutual correlation of components of interferences to work of tonal rail circuits
Journal Title: Інформаційно-керуючі системи на залізничному транспорті - Year 2018, Vol 23, Issue 3
Abstract
Tonal rail circuits work in the conditions of simultaneous influence of interferences of different type. These interferences in some cases lead to failures in operation of traveling receivers. For increase in their noise stability it is reasonable to use methodology of optimum reception of signals. Basic operation of processing of entrance additive mix of signal and interferences at such methodology is calculation of mutual correlation function of this mix and basic signal. However in this case there are cross-correlation components of interferences influencing final estimates of parameters of useful signal and these interferences. The purpose of this work is the research of conditions under which the specified cross-correlation components have negligible influence on the specified final estimates. It is shown that in the conditions of regular operation of rail circuits such influence really is negligible. Need of consideration of ways of simplification of means of processing of information signals taking into account the opportunities given by the elicited fact is noted.
