Simulation of Hybrid System Phase and Clock Synchronization PM-Signals

The simulation technique ’s models of hybrid synchronization system 2-PM signals such as Costas scheme and the delay tracking scheme were developed in the SystemVue. Processes simulating of the phase locking in the Costas loop and the clock synchronization in the delay locked loop scheme were done with the simulated impact of additive white Gaussian noise on the input signal and for the different type of discriminator. As a result of the simulation technique the dependences of the time of the transition process and steady-state values of the phase difference between the input signal carrier and common-mode signal from the controlled generator vs managed-noise with various precision of frequency capture, as well as the density of the probability distribution of the tracking errors at the different value of the signal-to-noise ratio were obtained.
