Optical phase locked loop for transparent inter-satellite communications F. Herzog1, K. Kudielka2,1 and W. B¨achtold 1 1Communication Photonics Group, Laboratory for Electromagnetic Fields. A novel type of optical phase locked loop (OPLL), optimized for homodyne inter-satellite communication, is presented.

The loop employs a conventional ° 3 dB optical hybrid and an AC-coupled balanced front end. No residual carrier transmission is required for phase locking. The loop accepts analog as well as digital data and various modulation formats.

Lombardo, to pass undistorted through the power amplifier without any need of back-off, which directly translates in power savings, can be performed by a digital phase locked loop (PLL) [12]. Analysis of Phase Locked Loop (PLL) influence on DQ impedance measurement in three-phase AC systems Abstract: AC small signal stability of three-phase systems can be analyzed using the load and source impedances in the d-q synchronous reference frame and many solutions have been recently proposed to measure d-q impedances.

As the induction heating power was working, its load resonant frequency constantly changes. In order to improve the efficiency of power supply, it requires that the inverter output frequency can follow changes in natural frequency of the load, namely the frequency tracking control.

Aiming at the deficiency of the frequency tracking control system, this paper presents a method that the Author: Yan Fang Li.

How to acquire the input frequency from an unlocked state. A phase locked loop (PLL) by itself cannot become useful until it has acquired the applied signal's frequency.

Often, a PLL will never reach frequency acquisition (capture) without explicit assistive circuits. mode. When Phase locked, the loop tracks any change in the input frequency through its repetitive action.

If an input signal v s of frequency f s is applied to the PLL, the phase detector compares the phase and frequency of the incoming signal to that of the output v o of the VCO. Angle ß is referred to as the topocentric angle. In all practi-cal situations relating to satellite interference, the topocentric and geo-centric angles may be assumed equal, and in fact, making thisassumption leads to an overestimate of the interference (Sharp, ).

Consider now S1 as the wanted satellite and S2 as the interferingsatellite. Design of phase-locked loop for communication system operations are specified by the reference (master) CFG0.

As the names imply, frequency locking is achieved when two signals are forced to be at the same frequency [math]\omega_1 = \omega_2[/math], while phase locking enforces [math]\phi_1 = \phi_2[/math].

However, given that [math]\dot{\phi}_i = \omega. This thesis covers the analysis, design and simulation of a low-power low-noise CMOS Phase-Locked Loop (PLL). Starting with the PLL basics, this thesis discussed the PLL loop dynamics and behavioral modeling.
