Focusing on the effect of nonlinearity-induced phase noise (NLPN), we find the auto-correlation and cross-correlation functions of the NLPN influencing different subcarriers, and propose a mitigation algorithm that takes advantage of these correlations so as to improve the overall system performance...
Phasor representation of phase noise A signal of angular velocityωO and peak amplitude VSPK is shown. Superimposed on this is an error signal of angular velocity ωm.ΔθRMS represents the RMS value of the phase fluctuations and is expressed in RMS degrees. In many radio systems, an ...
For digital systems, the integrated phase noise can be converted and expressed as phase jitter (phase noise in the time domain). Please note that phase noise just indicates short time frequency stability. If one needs to confirm long time frequency stability, one needs to refer to the ...

System and Method for Scrambling the Phase of the Carriers in a Multicarrier Communications SystemSystem and Method for Scrambling the Phase of the Carriers in a Multicarrier Communications SystemA system and method that scrambles the phase characteristic of a carrier signal are described. The scrambl...
Since specifications for Synchronous Optical Network (SONET) systems call out for low phase noise close to the carrier (1 kHz), these SAW sources are well-suited for SONET and synchronous-digital-hierarchy (SDH) applications. The 622-MHz oscillators, for example, exhibit close-in phase noise ...
As 5G, and especially 6G, push into ever-higher frequencies, phase noise presents an increasing problem. Disclosed are procedures and modulation schemes to mitigate phase noise and
