In a method for fractal coding of signals, in which a domain block d is investigated for a range block r to be transmitted from an original signal, so that, after using the calculation rule r*&equals;v&middot;d&plus;b, an approximated range block r* is generated, v&middot;d being a linear function and b being an offset vector, the offset vector b in general has different components b&equals;(b,, b,, . . . , b,) the offset vector b preferably being composed of weighted orthogonal basic functions of an orthogonal transformation.

Process for transmitting a signal

A signal is divided by windows into successive blocks that overlap at least by 50% and signal sections contained in the blocks are evaluated by analysis windows. The signal sections contained in the blocks are subjected to a transformation which permits sub-sampling with compensation of the aliasing components such as, for example, the 'time domain aliasing cancellation' method. The spectra resulting from the transformation are subsequently coded, transmitted, decoded after transmission and changed back to signal sections by re-transformation. The blocks including the signal sections are evaluated by synthesis windows and are joined together in an overlapping fashion. The window functions of the synthesis windows are determined in dependence on the window functions of the corresponding analysis windows in the overlap region.
