digital transmission for example digital mobile radio systems such as the umts 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 provided with correction factors the correction factors serving to equalize different power levels of the received signal application_number US 13484302 A description for a better understanding of the approach according to the invention and of the system model on which the following description is based reference is firstly made to fig2 which illustrates a simplified block diagram of a rake receiver for a transmission with ds cdma direct sequence code division multiple access for a linearly distorting channel as is known per se to the person skilled in the art after traversing a receiving filter 1 an input signal coming from an antenna is processed for this purpose in paths the so called fingers f 0 f i f l 1 of the rake receiver comprising a plurality of devices in particular for delay 2 despreading 3 and channel estimation 4 the time.
