On Phase Noise Suppression in Full-Duplex Systems [PDF]
, 2014 Oscillator phase noise has been shown to be one of the main performance limiting factors in full-duplex systems. In this paper, we consider the problem of self-interference cancellation with phase noise suppression in full-duplex systems. The feasibility

Oscillator phase noise: a tutorial [PDF]
IEEE Journal of Solid-State Circuits, 2000 Linear time-invariant (LTI) phase noise theories provide important qualitative design insights but are limited in their quantitative predictive power. Part of the difficulty is that device noise undergoes multiple frequency translations to become oscillator phase noise.

A Comprehensive Experimental Emulation for OTFS Waveform RF-Impairments
Sensors, 2022 The orthogonal time-frequency space (OTFS) waveform exceeds the challenges that face orthogonal frequency division multiplexing (OFDM) in a high-mobility environment with high time-frequency dispersive channels.

Phase Noise Modeling of Opto-Mechanical Oscillators [PDF]
, 2010 We build upon and derive a precise far from carrier phase noise model for radiation pressure driven opto-mechanical oscillators and show that calculations based on our model accurately match published phase noise data for such oscillators.

Influence of phase noise and interchannel interference on the performance of optical heterodyne FSK receiver [PDF]
Serbian Journal of Electrical Engineering, 2003 The moments approach is generally considered a systematic way to perform the analysis of coherent optical systems. Exact moments of the filtered signal corrupted by phase noise enable the construction of the Gaussian quadrature rule, which may be used to

Estimation of Phase Noise in Oscillators with Colored Noise Sources [PDF]
IEEE Communications Letters, 2013 In this letter we study the design of algorithms for estimation of phase noise (PN) with colored noise sources. A soft-input maximum a posteriori PN estimator and a modified soft-input extended Kalman smoother are proposed. The performance of the proposed algorithms are compared against those studied in the literature, in terms of mean square error of ...

Performance of DPSK Signals with Quadratic Phase Noise
, 2004 Nonlinear phase noise induced by the interaction of fiber Kerr effect and amplifier noises is a quadratic function of the electric field. When the dependence between the additive Gaussian noise and the quadratic phase noise is taking into account, the ...
