A device and associated method for passing parameters to a finger in a rake receiver are disclosed. The finger is initially operated with a first parameter set which is held in a first memory area (PAR_RAM). To change the parameter set, a second parameter set is loaded into a second memory area (PAR_CHG_RAM), a check is carried out to determine whether a switching condition (SCHED_RAM) is satisfied, and if it is an access for that finger is switched (MUX) from the first memory area (PAR_RAM) to the second memory area.

In a method for carrying out a plurality of correlation procedures in a mobile radio system, sample values which have been written to a data memory (DS) are read using a predetermined reading rule. Two correlation procedures are carried out on the basis of the sample values which have been read. This reading rule is in this case independent of the correlation procedure to be carried out.

Method and device for carrying out a plurality of correlation procedures in a mobile telephony environment

Correlations between the received signal to which pilot symbols have been applied at the transmitter end, and a correlation signal which contains the pilot symbols are carried out in the receiver in order to determine a path delay profile. Averaging processes are carried out over two or more delay profiles obtained in this way. Evaluations are carried out in one or more threshold value selection units () on two or more averaged delay profiles with the aim of path selection. The parameters which govern the correlations and/or the averaging processes and/or the evaluations, and/or the repetition interval of these calculations are set as a function of the relative speed between the transmitter and the receiver, the frequency error between the carrier frequency of the received signal and the reference frequency that is set at the receiving end, and the noise level of the received signal. In the case of reception from two or more base stations, a final path selection is made in a finger allocation unit ().

A method and apparatus for detecting paths of a received signal by analyzing a delay power profile of the received signal comprises a detection of peaks in the delay power profile by a peak detector having a threshold that is set based upon the noise environment. Peaks detected by the peak detector are passed to a data path detector having second threshold set at a power level higher than the threshold in the peak detector. In one embodiment, a third threshold is set within a filter to suppress secondary maxima created by the generation of the delay power profile. The detected paths may set in a rake type receiver.
