The effect of AM noise on correlation phase-noise measurements [PDF]
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2007 We analyze the phase-noise measurement methods in which correlation and averaging is used to reject the background noise of the instrument. All the known methods make use of a mixer, used either as a saturated phase detector or as a linear synchronous detector. Unfortunately, AM noise is taken in through the power-to-dc-offset conversion mechanism that

Discrete-Time Models and Performance of Phase Noise Channels
IEEE Open Journal of the Communications SocietyThis paper deals with the phase noise affecting communication systems, where local oscillators are employed to obtain reference signals for carrier and timing synchronizations. The most common discrete-time phase noise channel model is analyzed, with the

Relation Between Delay Line Phase Noise and Ring Oscillator Phase Noise [PDF]
IEEE Journal of Solid-State Circuits, 2014 The phase noise of a ring oscillator can be obtained by multiplying its open-loop phase noise by a simple shaping function. The shaping function is computed using first principles and is applicable to both flicker-noise-induced and white-noise-induced phase noise, leading to compact equations for ring oscillators.

Phase noise and amplitude noise in DDS [PDF]
2012 IEEE International Frequency Control Symposium Proceedings, 2012 Their article reports on the measurement of phase noise and amplitude noise of direct digital synthesizers (DDS), ultimately intended for precision time and frequency applications. The DDS noise S ϕ (f) tends to scale down as 1/ν 0 2, until the noise hits the limit due to the output stage.

A NEW PHASE NOISE DETECTION METHOD
Electrica, 2015 Phase noise is one of the most important parameters in many oscillators. Detecting accurately phase noise for oscillators has importance significance. In this paper, based on correlation operation detection phase noise for oscillators was proposed.

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.
