Abstract
The invention relates to a method of transmitting calls in a cellular type telecommunications system using a plurality adjacent carrier frequency bands and in which a first cell or a first site uses only a fraction of said frequency bands, the transmitted signals being subjected to peak clipping prior to application to an amplifier of a transmitter system in order to optimize the efficiency of the amplifier. Prior to being applied to the input of the amplifier, the signals () to be transmitted for the first cell (or first site) are subjected to filtering () so that the power density of the peak-clipping noise is not eliminated in adjacent frequency bands (f, f) that are unused by said first cell.
