1. A method for generating a variable-band OFDM (Orthogonal Frequency Division Multiplexing) signal, the method comprising:

  • forming a modulating digital OFDM signal by;

    associating at least two of a first plurality of components relating to user messages to be transmitted, a second plurality of components relating to signalling to be transmitted, a third plurality of components relating to pilot carriers to be transmitted so as to form a fourth plurality of componentscoding information about said variable-band OFDM signal so as to form a plurality of information components; and

    repeatedly or periodically summing said information components about said variable-band OFDM signal with at least one of said first and second and third and fourth pluralities of components; and

    modulating said modulating digital OFDM signal to output said variable-band OFDM signal.
