Optical Phase-Locked Loop Technologies in Communication Systems

Optical phase-locked loops (OPLLs) are closed-loop control systems that stabilise and synchronise the phase of a slave laser with respect to a reference source, enabling coherent optical generation ...

Good behavioral model simulation: key to predicting first-order PLL synthesizer performance (Part 1 of 2)

In this article, the phase noise of a closed-loop, phase-locked loop (PLL) synthesizer is simulated using Agilent RF Design Environment (RFDE) and Advanced Design System (ADS) tools. The critical ...

Expert Advice: Quasi-Coherent Delay Lock Loop Tracking and Generalized Binary Coded Symbols in Multipath

The original GPS signals, and indeed most GPS signals including L5, utilize conventional pseudonoise (PN) signal code division multiple access (CDMA), some with both in-phase and quadrature-phase ...
