FIELD: physics.
SUBSTANCE: frequency band is divided into N sub-bands, where is N a whole number greater than or equal to two; an OFDM (Orthogonal Frequency Division Multiplexing) technique is carried out on each of said sub-bands; and calculations are carried out based on each sub-band. The disclosed method is characterised in that the calculations based on each sub-band are independent from the calculations based on the other sub-bands, and said sub-bands are dynamically activated and allocated. The invention also relates to modulation and demodulation devices for realising said method.
EFFECT: easier synchronisation.
