ABSTRACT:
The invention relates notably to a method for transmitting frames on a radio communication channel (RCC), the frames comprising a succession of bursts (B1, . . . , Bn) modulated with at least two different modulation schemes (M1, M2, M3) having different modulation efficiencies, each modulation scheme (M1, M2, M3) having a corresponding average transmitted power.The method according to the invention comprises the steps of:mapping information to be transmitted to modulation symbols using one of the modulation schemes (M1, M2, M3);filtering the modulation symbols using a digital transmission filter with a set of coefficients, the set being chosen from at least two sets of coefficients depending on the modulation scheme (M1, M2, M3) used at the mapping step, the product of the average transmitted power and the gain of the digital transmission filter being smaller than a predefined value for all modulation schemes (M1, M2, M3).
