Abstract: 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.

Abstract: 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 (22.1, 22.2) 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.

Abstract: 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.

At least a part of the at least one path component is removed or reduced by utilizing an impulse response characteristic of the path component in the delay profile. Following this, the rake fingers of the receiver are placed using the modified delay profile.

Abstract: In a method and an arrangement for checking the tightness of a vessel (10), especially of a tank-venting system of a motor vehicle, the vessel (10) is charged with a pressure generated by a motor-driven pressure source (30) and the motor current is determined. A reference leak (36) is selectively driven by a switchover valve (32) and is charged with a corresponding pressure and the motor current is determined.

Abstract: A method for calculation of path weights for the equalization of a data signal that is transmitted via a data channel whose power is regulated in a RAKE receiver is disclosed. In the method, at least one uncorrected path weight is calculated for the data signal that is transmitted via the data channel, using channel estimation results that have been obtained on the basis of a common pilot channel. The uncorrected path weight is corrected by multiplying it by a correction factor that contains a ratio of a data-channel-specific gain estimation to a pilot-channel-based gain estimation.
