Abstract
A method is presented for determining an actual pulse position in a signal. This signal comprises a plurality of successive frames, wherein each frame has length L and contains one pulse with width W, a number of discrete possible pulse positions being considered within in each frame which is at least L/W. The method comprises the steps of a) sampling the signal at a sampling rate below L/W with a varying sampling phase such that the whole frame length L is covered, b) obtaining a set of samples with at least one at each of the possible pulse positions, c) correlating this set of samples with a set of one or more predetermined values and d) determining the actual pulse position from said correlation. The method provides a low-complex signal acquisition solution in a receiver and is particularly useful for low-complexity and low-power IR-UWB transceivers.
