چکیده
In this paper, a new method for the separation of noise categories based on Four-Wave Mixing is presented. The theoretical analysis grounded in Gaussian Noise model and verified by split step simulations. react differently to introduced perturbations, performing set perturbations behaviour different can be separated means least-square fitting. Given ASE independent induced it possible separate contributions. includes constant variable power perturbations. estimation discussed from two points view: NSR evolution post-DSP processing, over spectral density notched region. only performed at reception, whereas approach along optical link if high resolution Optical Spectrum Analyzer available. Additionally, we perform simple experimental verification considering WaveLogic 3 transceivers NSR, successfully estimating

Frequency-domain analysis of nonlinear and linear integrators
In this paper, frequency-domain analysis based on frequency sweep method is presented for a nonlinear double integrator and a new linear integrator. All the two types of integrators can estimate the onefold and double integrals of a signal synchronously. With respect to the linear double integrator, the nonlinear integrator has better estimation performance and stronger robustness. Importantly,...
متن کاملVolatility and Risk Estimation with Linear and Nonlinear Methods Based on High Frequency Data
Accurate volatility predictions are crucial for the successful implementation of risk management. The use of high frequency data approximately renders volatility from a latent to an observable quantity, and opens new directions to forecast future volatilities. Our goals in this paper are: (i) to select an accurate forecasting procedure for predicting volatilities based on high frequency data fr...
متن کاملUKF Based Nonlinear Filtering for Parameter Estimation in Linear Systems with Correlated Noise
Based on the Unscented Kalman Filter (UKF), the nonlinear filter is presented for parameter estimation in linear system with correlated noise where the unknown parameters are estimated as a part of an enlarged state vector. To avoid the computational burden in determining the state estimates when only the parameter estimates are required, a new form of UKF, where the state consists only of the ...
متن کاملaliasing in ?-? domain and attenuation of aliased linear noise in this domain
one of the common problems in reflective seismic records is the existence of coherent linear and random noises which cause covering of the most important parts of reflective signals; therefore, it is necessary to attenuate them by processing methods. several processing techniques have been devised for attenuation of coherent linear noises and linear radon or ?-? transform is a powerful techniqu...
متن کاملNoise-aided nonlinear Bayesian estimation.
Estimation on a noisy signal observed by a nonlinear sensor taking the form of a threshold quantizer is considered. The optimal Bayesian estimator with minimal error is derived in this nonlinear setting. The existence of conditions where the performance of this estimator can be improved by raising the level of noise is established, both theoretically and numerically. These results constitute a ...
