Quasi-nonparametric blind inversion of Wiener systems
Anas Abu Taleb, J. Sole, Christian Jutten · IEEE Transactions on Signal Processing · 2001
An efficient procedure for the blind inversion of a nonlinear Wiener system is proposed. We show that the problem can be expressed as a problem of blind source separation in nonlinear mixtures for which a solution has been previously proposed. Based on a quasi-nonparametric relative gradient descent, the proposed algorithm can perform efficiently even in the presence of hard distortions.
