Patent ID: 7016397

Claim:
A method of processing multipath-propagated signal components in a communications system, in which a signal transmitted on a radio channel of the communications system is received in a RAKE receiver and an impulse response of the radio channel is formed in a delay estimator of the RAKE receiver on the basis of the received signal by correlating the received signal with a first matched filter, the method comprising: locating one or more taps having the highest signal energy in the impulse response, matching the one or more taps to a second matched filter shorter than the first matched filter, calculating a weighting value for the impulse response using statistical methods on the basis of the one or more taps in the second matched filter, comparing a deviation between the weighting value and a centre point of the second matched filter with a threshold value set for the deviation, moving the second matched filter forward when the deviation exceeds the threshold value set for exceeding the deviation, moving the second matched filter backward when the deviation undershoots the threshold value set for undershooting the deviation, and repeating the calculating a weighting value, comparing a deviation, moving the second matched filter forward and moving the second matched filter backward during reception of the signal.
