Abstract
A method for estimating a plurality of delay values in a multi-path communication signal. Correlation values are generated that correspond to a plurality of delay values associated with the multi-path communication signal. A first power-delay profile (PDP) sequence is produced from the correlation values and is used to estimate a first delay value. A first reference PDP sequence is generated based on a predefined PDP sequence and the first PDP sequence. The first reference PDP sequence is removed from the first PDP sequence so as to remove at least a portion of the contributions to the first PDP sequence from the first delay value, and to provide a second PDP sequence. A second value is estimated based on the second PDP sequence.
