Abstract
The invention relates to a reception method and a receiver comprising means where a received signal is sampled, and means where the mutual delays of the transmissions contained in the signal and the strengths of the transmissions are measured from the received signal, said transmissions originating in one or more transmitters. In order to ensure reception of high quality, the receiver according to the invention comprises means, the input of which, is the sampled signal, and in which an estimate is calculated from the samples for each desired transmission on the basis of all samples which have arrived during a certain monitoring period, and that whenever a new sample arrives at the input of the means, the means updates the calculated estimates on the basis of the new sample.
