PROBLEM TO BE SOLVED: To provide a method for transmitting telecommunication signals using a power amplifier that is associated with a linearization means and simultaneously amplifies a plurality of signals for modulating different carriers. SOLUTION: The method of transmitting telecommunication signals uses a power amplifier, that is associated with linearization means for simultaneously amplifying a plurality of signals for modulating different carriers. A composite signal consisting of the carriers is clipped on the upstream side of the amplifier. A clipping threshold depends on the sum of the powers of various signals to be transmitted, and also the operating parameter of the amplifier depends on the sum of the powers, in order to maintain optimum efficiency in the amplifier and/or to minimize a power margin, namely the difference between saturation power and average operating power.
