Improving the accuracy of the time and frequency signal transmission over coaxial cable

Abstract

This paper assesses the effect of wide temperature differences of cable segments on the stability of the transmitted frequency. Paper presents a method for determining the integral temperature of a long cable, as well as a method for compensating the introduced instability of the transmitted frequency. A method for stabilizing the integral temperature of a long coaxial cable using a proportional-integral-differentiating algorithm (PID) algorithm and a distributed heater is also proposed.
