Adaptive filtering is useful in any application where the signals or the modeled system
vary over time. The configuration of the system and, in particular, the position where
the adaptive processor is placed generate different areas or application fields such as:
prediction, system identification and modeling, equalization (deconvolution, reverse
filtering, inverse modeling), cancellation of interference, etc. which are very important
in many disciplines such as control systems, communications, signal processing,
acoustics, voice, sound and image, etc....
