DETERMINATION OF THE TIME DELAY AND/OR POWER OF A MULTICARRIER SIGNAL

The invention relates to a method of determining the time shift and/or the power of a received signal incorporating a reference sequence (3) and transmitted by multicarrier modulation on a set (M) of carriers spaced from each other by a distance n f where n is a natural integer and f is a constant....

Beschreibung
Zusammenfassung:	The invention relates to a method of determining the time shift and/or the power of a received signal incorporating a reference sequence (3) and transmitted by multicarrier modulation on a set (M) of carriers spaced from each other by a distance n f where n is a natural integer and f is a constant. An inverse Fourier transform is applied to the phase variations between components of the signal carried by carriers separated by k f for consecutive values of k in order to obtain the impulse response (RI) of the signal and the time shift τ0 and/or the power of the received signal is/are determined from the impulse response by observation of the highest level amplitude peak.
