Digital signal, transmission method, receiving method, receiving device and application thereof that can be received by the receiver demodulated by the restoring side band amplitude module signal

摘要

The invention relates to a digital data signal intended to be received in particular by MABLR demodulator receivers. The signal of the invention comprises a pilot frequency fp (41), a blank frequency band fp at fp + P.DELTAf at (42) bearing no useful signal and a plurality of carrier frequencies fp + P.DELTAf at fp + Q.DELTAf (43), each of said carrier frequencies being modulated by separate data elements representative of a source digital signal to be transmitted. The plurality of carrier frequencies forms, for example, a COFDM signal. The pilot frequency (41) makes it possible to demodulate the plurality of carriers (43) using a conventional MABLR demodulator. The blank tape (42) allows proper operation of the receiver recovery circuits. / P
