In the process of specifying and modelling data structures for wide classes of real-time applications (signal-processing, pattern recognition, communications engineering) it has become a helpful tool to choose these structures as algebras which allow a group of automorphisms acting on the set of data.

With this data algebras being suchwise enhanced many of the above mentioned applications find a natural description.

In this lecture we will show that this description can successfully be used for a unifying approach to fast algorithms for many applications e.g. by reproducing the known classes of FFT's. The concept of the generalized Fourier-Transform can also be used in this context to generate such algorithms almost mechanically, as we will show in some examples.
