    Abstract: The invention relates in general to systems for digital transmission, for example digital mobile radio systems such as the UMTS (Universal Mobile Telecommunications System) and in particular to the receiving-end estimation of parameters which are required for retrieving the data. An object of the invention resides, in particular, in indicating an efficient way which, particularly in the case of CDMA systems with power control, ensures estimates of higher quality than with methods of the prior art, and simultaneously largely avoids a substantial increase in the complexity of system implementation. For this purpose, the invention proposes a method for improving the reception of a CDMA receiver based on a parameter estimation method, as well as a correspondingly adapted CDMA receiver, in which the estimates are produced by processing received values (yiÄkÜ) provided with correction factors (s), the correction factors (s) serving to equalize different power levels of the received signal.
