Abstract
A communication entity includes an antenna array with different antennas for transmitting and receiving. A combined transmission signal is generated by superposition of the transmission signals from the different antennas. Power amplifiers are each connected to one antenna. A control unit controls an input signal of each power amplifier and generates a directional combined transmission signal by controlling the phase and amplitude of each antenna. The control unit determines a total output power for the directional combined transmission signal, and determines a saturation state in which at least one power amplifier of the connected antenna is operating in a saturation state at maximum power. When the saturation state is detected, the control unit controls an input signal of at least one non-saturated power amplifier so the power emitted by at least one corresponding antenna connected to the at least one non-saturated power amplifier is increased.
