Abstract
The invention relates to a method for transmitting data over a carrier current using a frequency band. According to said method: the frequency band is divided into N sub-bands, N being a whole number higher 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 inventive 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 carrying out said method.
