Abstract
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*=v.multidot.d+b, an approximated range block r* is generated, v.multidot.d being a linear function and b being an offset vector, the offset vector b in general has different components b=(b.sub.1, b.sub.2, . . . , b.sub.n) the offset vector b preferably being composed of weighted orthogonal basic functions of an orthogonal transformation.
