Linear modeling in the presence of nonlinear distortions

IEEE Transactions on Instrumentation and Measurement, 2002
In this paper we set up a framework to deal with nonlinear distortions in a linear modelling framework. The nonlinear system is replaced by a linear system plus a noise source. The properties of this representation are given, and a measurement technique to extract the linear model and the noise variance is developed. Eventually the different aspects of

Identification of linear systems in the presence of nonlinear distortions

IEEE Transactions on Instrumentation and Measurement, 2001
This 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 ...

MEASUREMENT AND MODELLING OF LINEAR SYSTEMS IN THE PRESENCE OF NON-LINEAR DISTORTIONS

Mechanical Systems and Signal Processing, 2002
In [3] the measurement and modelling of linear systems in the presence of non-linear distortions has been studied for a special class of periodic excitation signals. This paper extends the theory of [3] to more general classes of (periodic) excitation signals.

From post-distortion to pre-distortion for power amplifiers linearization

IEEE Communications Letters, 2003
This letter presents a new method of digital adaptive pre-distortion for linearization of power amplifiers (PA). The method is derived from a post-distortion approach which identifies the PA inverse function. This approach leads to the minimization of a quadratic function of the polynomial coefficients in the case of a polynomial predistorter form and ...

Rate-distortion in near-linear time

2008 IEEE International Symposium on Information Theory, 2008
We present two results related to the computational complexity of lossy compression. The first result shows that for a memoryless source Ps with rate-distortion function R(D), the rate-distortion pair (R(D) + gamma, D + isin) can be achieved with constant decoding time per symbol and encoding time per symbol proportional to C1(gamma)isin-C2(gamma).
