In order to study the behavior of the KRLS, we consider some nonlinear channel equalization set-ups similar to the ones used in Section 188.8.131.52.2. In the first experiment, the nonlinear channel consists of a linear filter:
and a memoryless nonlinearity
The input signal that was fed to the channel followed the Gaussian distribution with zero mean and unity variance. At the receiver end of the channels, the signal is corrupted by white Gaussian noise and then observed as . The level of the noise was set to ...
