METHOD OF DETERMINING PARAMETERS OF A SIGNAL OF OFDM TYPE AND ASSOCIATED RECEIVER

Abstract The invention relates to a method of determining parameters of a signal of OFDM type in a receiver comprising a tuner and a demodulator, as well as such a receiver. The method comprises the steps: (a) programming the demodulator with a particular value of the FFT mode parameter; (b) varying exhaustively other parameters of the signal for this particular value of FFT mode parameter and a particular value of the guard interval; (c) verifying the absence of lock-on, even temporary of the carrier recovery loop during the phase of variation; (d) repeating steps (a) to (c) with any FFT mode, in case of absence of lock-on; (e) storage of the configurations of parameters corresponding to temporary lock-ons; and (f) variation of the guard interval value for each of these configurations, until permanent lock-on of the carrier recovery loop is detected.
