Some modern applications require an extraordinary large amount of complexity in signal processing algorithms. For example the 3rd generation of wireless cellular systems is expected to require 1000 times more complexity when compared to its 2nd generation predecessors and future 3GPP standards will aim for even more number-crunching applications. Video and multimedia applications do not only drive the complexity to new peaks in wired and wireless systems but also in personal and home devices. Also in acoustics modern hearing aids or algorithms for dereverberation of rooms blind source separation and multichannel echo cancellation are complexity hungry. At the same time the anticipated products also put on additional constraints like size and power consumption when mobile and thus battery powered. Furthermore due to new developments in electro-acoustic transducer design it is possible to design very small and effective loudspeakers. Unfortunately the linearity assumption does not hold any more for this kind of loudspeakers leading to computationally demanding nonlinear cancellation and .
