摘要： 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. In the case of reception from two or more base stations, a final path selection is made in a finger allocation unit (40).

摘要： A quadrature modulator including two mixers to which two carrier signals are applied and to each of which a modulating signal is applied, output signals of the mixers being applied to a combiner to constitute a modulated signal. A defect estimator for the modulator detects a first signal representative of the instantaneous power of the modulated signal, generates a second signal representative of a reference envelope obtained from the modulating signals, and corrects the amplitude of one of the first and second signals in accordance with the mean amplitude difference observed between this amplitude corrected signal and the other signal. A processor supplies from the observed amplitude difference between the amplitude corrected signal and the other signal, at least one signal relating to the defect.

摘要： In the method for rake finger placement in a receiver, a delay profile of a multipath transmission channel is determined, wherein the signal strength is distributed over a plurality of delay times in at least one path component in the delay profile. 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.

摘要： 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.
