Nonlinear cross-talk mitigation in polychromatic parametric sampling gate.
نویسندگان
چکیده
New technique for cancellation of nonlinear cross-talk in polychromatic parametric sampling gate is described and quantified. The method relies on a newly derived look-up table method that achieves equalization and suppresses nonlinear response associated with parametric sampling operation. The new cancellation scheme is implemented in a framework of a specific parametric photonics assisted analog-to-digital conversion (ADC) copy-and-sample-all (CaSA) architecture. A 20 dB improvement in total harmonic distortion is demonstrated experimentally.

Optimal Nonlinear Energy Sinks in Vibration Mitigation of the Beams Traversed by Successive Moving Loads
Optimal Nonlinear Energy Sink (NES) is employed in vibration suppression of the beams subjected to successive moving loads in this paper. As a real application, a typical railway bridge is dynamically modeled by a single-span beam and a traveling high-speed train is simulated by a series of successive moving loads. Genetic algorithm is employed as the optimization technique and optimal paramete...
متن کاملCross talk of wavelength-multiplexed quasi-infinite holograms.
The cross talk of wavelength-multiplexed quasi-infinite (written in polychromatic light) holograms is evaluated. Under plausible conditions this cross talk is negligible. The typical information capacity limit of such holograms is evaluated as 10(12) bits for a 1-cm(3) volume.
متن کاملEffectiveness of Check Dams in Management and Mitigation of Floods in Quran Gate of Shiraz with semi-Distributed Rainfall-Runoff Simulation
The flood on March 25, 2019 in the Quran Gate of Shiraz led to heavy human and financial losses. Studies of the current condition of the 25 km2 semi-urban watershed of the mentioned area were performed using the SCS semi-distributed rainfall-runoff model. Due to the big difference in average elevation of the Quran Gate watershed with synoptic and rain gauge stations in Shiraz, the precipitation...
متن کاملHemodynamic modelling of BOLD fMRI - A machine learning approach
Non-linear hemodynamic models express the BOLD signal as a nonlinear, parametric functional of the temporal sequence of local neural activity. Several models have been proposed for this neural activity. We identify one such parametric model by estimating the distribution of its parameters. These distributions are themselves stochastic, therefore we estimate their variance by epoch based leave-o...
متن کاملAnalysis and mitigation of phase noise and sampling jitter in OFDM radio receivers
This article addresses the analysis and digital signal processing (DSP)-based mitigation of phase noise and sampling clock jitter in orthogonal frequency division multiplexing (OFDM) radios. In the phase noise studies, the basic direct-conversion receiver architecture case is assumed with noisy downconverting oscillator. In the sampling jitter case, on the other hand, the so-called direct-radio...
