| Abstract |
| The presence
of non-linear effects in adaptive filtering was observed
previously in a wide sense stationary equalization scenario
with narrowband interference. The influence of a variety
of parameters on the magnitude of such non-linear effects
was also investigated. While the adaptive filter appears
to exhibit behavior that one would expect in a wide sense
stationary scenario, we show here that the adaptive filter
is actually tracking a time-varying target solution. It
is the latter property that is responsible for the performance
improvement of the adaptive filter over the performance
of the corresponding Wiener filter. |
