Claim One:
1. A procedure for estimating unknown amplification factors (g a (b) ) of a received CDMA Signal (r(&ngr;)), which encompasses a plurality of code channels, in which, respectively, an incoming signal (s a (b) (l)) of a symbol plane with a splitter code (w a (b) (&ngr;)) is split into a chip plane, having the following procedure steps: formation of a cost function (L) dependent upon estimated values (&gcirc; a (b) ) of all unknown amplification factors (g a (b) ), partial differentiation of the cost function (L) according to estimated value (&gcirc; a (b) ) of the unknown amplification factors (g a (b) ), formation of a matrix-vector-equation on the basis that all partial differentials of the cost function (L) are zero and thus a minimum of the cost function is present, and the computation of at least some of the matrix coefficients (A a,&mgr; (b,&lgr;) ) of the matrix-vector-equation with a correlation function on the symbol plane.
