Abstract: A COFDM demodulator or analogue comprising a fast Fourier transform circuit analyzing a received signal in a window corresponding to a symbol, each symbol conveying several phase- and/or amplitude-modulated carriers, some of which are signaling carriers, and a circuit for positioning said window. The circuit for positioning said window uses the non demodulated signaling carriers.
