Phase Noise in OFDM

, 2022
Orthogonal frequency division multiplexing (OFDM) technique provides high data rate with high spectral efficiency for operating close to the Shanon capacity bounds. With the advantages of simple channel equalization, robustness against frequency selectivity of the channel, and efficient implementation, this is a widely deployed technique.

Noise beating in hybrid phase-sensitive amplifier systems

, 2014
We investigate the effect of noise loading in a hybrid phase-sensitive amplifier system, analyzing the effect of noise beating between the signal and idler waves coupled in a parametric amplifier.

Phase Noise Influence on the Transfer Function Estimation of Analog to Digital Converters Using the Histogram Method

IEEE Access
The presence of phase noise in the signal generator used to characterize analog-to-digital converters (ADCs) affects the precision of the estimates made. This work focuses specifically on estimating the transition voltages of ADCs made with the Histogram

Optical signal to noise ratio improvement through unbalanced noise beating in phase-sensitive parametric amplifiers

, 2014
We investigate the beating of signal and idler waves, which have imbalanced signal to noise ratios, in a phase-sensitive parametric amplifier. Imbalanced signal to noise ratios are achieved in two ways; first by imbalanced noise loading; second by ...
