A Wiener system is a linear time-invariant filter,
followed by an invertible nonlinear distortion. Assuming
that the input signal is an independent and
identically distributed (iid) sequence, we propose
an algorithm for estimating the input signal only
by observing the output of the Wiener system. The
algorithm is based on minimizing the mutual information
of the output samples, by means of a steepest
descent gradient approach.^^^^
