Harmonic Bandpass Distortion of a Chebyshev Nonlinearity
IEEE Transactions on Communications, 1976Harmonic distortion imparted to the sidebands of an amplitude-modulated carrier by a system described by a Chebyshev series is evaluated. Sideband distortion increases with modulation depth but decreases with low carrier level, when even-harmonic contributions disappear.

Nonlinear filter for inversion of channel distortion
ICASSP '78. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005The ill-posed nature of direct deconvolution has prevented its use in applications such as channel equalization or inversion of transducer distortion. In this paper we discuss the use of a recursive nonlinear filter. The design of the proposed filter is accomplished in two stages.

Feedback and nonlinear distortion
Proceedings of the IEEE, 1981The effect of linear negative feedback on the normalized coefficients of a power series is evaluated. For large loop gain, desensitization tends to proceed with the power of the particular closed-loop term.

Nonlinear distortions of rotating chiral solitons
Physical Review D, 1988We show that the rotation in isospace of a chiral soliton induces nonlinear distortions of the chiral field leading to a band cutoff phenomenon. In models in which quarks are coupled to the chiral field, this band cutoff is caused by the alignment of the quark isospins about the rotation axis, which induces a corresponding change in the symmetry of the

Shape restoration of nonlinear distorted images
Proceedings of the 12th IAPR International Conference on Pattern Recognition (Cat. No.94CH3440-5), 2002Image shape restoration based on mathematical transformation is a successful approach to nonlinear distortions in computer vision, robot vision and pattern recognition. The key of this process is to find the distortion function and its inverse function. Usually, the distortion function is unknown or unclear.

Adversarial autoencoder for reducing nonlinear distortion
2018 Asia-Pacific Signal and Information Processing Association Annual Summit and Conference (APSIPA ASC), 2018A novel post-filtering method using generative adversarial networks (GANs) is proposed to correct the effect of a nonlinear distortion caused by time-frequency (TF) masking. TF masking is a powerful framework for attenuating interfering sounds, but it can yield an unpleasant distortion of speech (e.g., a musical noise).

Sensitivity Analysis of Nonlinear Behavior with Distorted Probability
SSRN Electronic Journal, 2013In this paper, we propose a sensitivity‐based analysis to study the nonlinear behavior under nonexpected utility with probability distortions (or “distorted utility” for short). We first discover the “monolinearity” of distorted utility, which means that after properly changing the underlying probability measure, distorted utility becomes locally ...

Detection of nonlinear distortion in audio signals
IEEE Transactions on Broadcasting, 2002Nonlinear distortion of a signal passing through a system may be caused by a number of factors. One of those factors, a limiter like transfer function, is considered. The nonlinear distortion causes a change in the probability density function (PDF) of the signal.

A new approach on nonlinearity distortion
5th International Conference on Telecommunications in Modern Satellite, Cable and Broadcasting Service. TELSIKS 2001. Proceedings of Papers (Cat. No.01EX517), 2002In this paper a new approach on nonlinearity distortion in amplifiers is given. For an amplifier is possible to establish a relationship between the output power at 1 dB compression and third order interception point for the classical approximation and for a new type of approximation based on modulus.

Identification of linear systems in the presence of nonlinear distortions
IEEE Transactions on Instrumentation and Measurement, 2001This paper treats the identification of linear systems in the presence of nonlinear distortions. It extends the theory developed for measurement setups where the input is exactly known and the output is observed with errors (output error framework) to measurement setups where both the input and output are observed with errors (errors-in-variables ...
