Phase noise due to vibrations in Mach-Zehnder atom interferometers
, 2006 Atom interferometers are very sensitive to accelerations and rotations. This property, which has some very interesting applications, induces a deleterious phase noise due to the seismic noise of the laboratory and this phase noise is sufficiently large ...

International Journal for Simulation and Multidisciplinary Design Optimization, 2020 To take advantage of the physical principles of determining parameters, such as frequency stability, noise and also alignment of optical signals, it is necessary to control complex systems.

Intrinsic noise-induced phase transitions: beyond the noise interpretation [PDF]
, 2003 We discuss intrinsic noise effects in stochastic multiplicative-noise partial differential equations, which are qualitatively independent of the noise interpretation (Ito vs.

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.

Electronics Letters, 1984 A formula is derived for the output phase noise of a mixer when both the radio frequency RF and local oscillator LO carriers are impaired by phase noise. The calculation uses test results obtained with three discrete carriers. An application of the noise formula to frequency synthesis is included.

Intrinsic 1/f device noise reduction and its effect on phase noise in CMOS ring oscillators [PDF]
, 1999 This paper gives experimental proof of an intriguing physical effect: periodic on-off switching of MOS transistors in a CMOS ring oscillator reduces their intrinsic 1/f noise and hence the oscillator's close-in phase noise. More specifically, it is shown

Convergence of phase noise in DPSK transmission systems by novel phase noise averagers
Optics Express, 2006 This investigation proposes a novel all-optical phase noise averager to reduce residual phase noise in the differential phase-shift keying (DPSK) transmission system with phase-preserving amplitude regenerators. The proposed phase noise averager is based on a phase-sensitive amplifier but does not require an extra phase-locking optical pump beam.

Phase and alignment noise in grating interferometers [PDF]
New Journal of Physics, 2007 Diffraction gratings have been proposed as core optical elements in future laser-interferometric gravitational-wave detectors. In this paper we derive equations for the coupling between alignment noise and phase noise at diffraction gratings. In comparison to a standard reflective component (mirror or beam splitter) the diffractive nature of the ...

Feedforward pilot-aided carrier synchronization using a DCT basis expansion [PDF]
, 2009 This contribution deals with phase noise estimation from pilot symbols. The phase noise process is approximated by an expansion of Discrete Cosine-Transform (DCT) basis functions containing only a few terms.
