DETERMINATION OF THE TIME DELAY AND/OR POWER OF A MULTICARRIER SIGNAL
摘要
The invention relates to a method for determining the time delay and/or power of a received signal incorporating a reference signal and transmitted by multicarrier modulation on a set (M) of carriers which are interspaced at a distance n<f, wherein n is a natural number and ?f is a constant. An inverse Fourier transformation (16) is applied to phase variations between components of the signal which are carried by carriers at a distance k.?f for consecutive values of k in order to obtain the pulse response (RI) of the signal and the time delay ?o and/or the power of the received signalis/are determined according to the pulse response by observing the highest amplitude peak.
