Abstract:
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 being an amplification factor 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), wherein the offset vector b is composed of weighted orthogonal basic functions tm of an orthogonal transformation, and wherein the mean square error e.sup.2 is used to determine the optimum domain block d, in which case the optimum values for the amplification factor v and the coefficients a.sub.m of the orthogonal basis vectors t.sub.m become: ##EQU17##anda.sub.m =R.sub.m -v.multidot.D.sub.mwhere: ##EQU18##
