Advanced Digital Nonlinear Distortion Compensation
Optical Fiber Communication Conference, 2015We review the recent progresses on the nonlinear perturbation pre-distortion including the modified nonlinear model for performance improvement and nonlinear terms combination for complexity reduction. With Nyquist nonlinear model, the performance shows even more improvement.

Unbiased reconstruction of nonlinear distortions
IMTC/2002. Proceedings of the 19th IEEE Instrumentation and Measurement Technology Conference (IEEE Cat. No.00CH37276), 2003When a signal goes through a system having a static, nonlinear transfer function, the output signal will be distorted. In addition, the detected output signal is usually contaminated by noise, due to the noisy environment. If we compensate the nonlinearity with its inverse, the expected value of the output signal will be different from it's original ...

Nonlinear independent component analysis with minimal nonlinear distortion
Proceedings of the 24th international conference on Machine learning, 2007Nonlinear ICA may not result in nonlinear blind source separation, since solutions to nonlinear ICA are highly non-unique. In practice, the nonlinearity in the data generation procedure is usually not strong. Thus it is reasonable to select the solution with the mixing procedure close to linear. In this paper we propose to solve nonlinear ICA with the "

Signal Distortion in Nonlinear Feedback Systems
Bell System Technical Journal, 1963This paper reports on some properties of the solutions to the functional equation $s_{2}(t) = \varphi[{\bf C}s_{2}(t) + s_{1}(t)],$ where ϕ is a nonlinear function, the operator C is a convolution, and s 1 is a known function belonging to a prescribed Banach space.

More on nonlinear distortion correction
IRE Transactions on Audio, 1961Further consideration is given to basic amplitude limitations which may apply to the complementary distortion method of nonlinear distortion correction. It is found, in disagreement with others, that points at which the differential gain is zero or infinite do not limit the amplitude over which complete correction is possible but that relative maxima ...

"Apparent bass" and nonlinear distortion
IRE Transactions on Audio, 1961A discrepancy between the "apparent bass" response heard by the average music listener and anechoic-chamber measurements has been noted for some small loudspeaker systems. This may be caused by the psychoacoustic response to the generation of harmonic distortion by the nonlinear suspension and the inhomogeneous flux gap density in a small speaker.

The Ear’s Own Nonlinear Distortion
1999A transmission system containing a nonlinearity produces harmonics when transmitting a pure tone. Such distortion products are often neither annoying nor audible, because they match almost totally with the fundamental. Musical tones are complex tones and consist of several harmonics.

Nonlinear Distortion in Feedback Amplifiers
IRE Transactions on Circuit Theory, 1962Consider a feedback amplifier F with a nonlinear output device T_0 and an open-loop amplifier A having the same gain and the same output device T_0 . If the gains of the forward amplifier u and feedback network \beta are independent of frequency, it is well known that under the usual conditions the nonlinear distortion \zeta of F due to T_0 is related ...
