Improved Phase Noise Compensation in OFDM Systems [PDF]
Radioengineering, 2022 Phase noise (PN) consists of common phase error (CPE) and inter carrier interference (ICI). In an OFDM symbol, CPE has the same impact on each subcarrier, which is easy to be suppressed.

Noise performance of frequency- and phase-locked CW magnetrons operated as current-controlled oscillators. [PDF]
, 2005 Low-power continuous wave ``cooker'' magnetrons driven from industrial-quality switch-mode power supplies have been frequency locked by driving them as current-controlled oscillators in a phase-lock loop (PLL).

Intelligent Sensors in Software: The Use of Parametric Models for Phase Noise Analysis
, 2006 Intelligent senors have attracted particular attention in the recent past. This paper argues that an “intelligent sensor” should be able to perform on-board signal processing within the sensor’s software in order to produce the optimal signal output.
