ABSTRACT:
A transmitter unit which is disposed between the first base station and the antenna arrangement contains a device for aggregate signal forming, a D/A converter and a transmission power amplifier. The first base station is connected on the output side to the device for aggregate signal forming such that a digital output signal of the first base station reaches the device for aggregate signal forming as the first input signal. The device for aggregate signal forming is connected on the output side to the antenna arrangement via the D/A converter and the transmission power amplifier such that an aggregate signal formed by the device for sum forming reaches the antenna arrangement, the aggregate signal being formed from the first digital input signal and a second digital input signal connected to the device for aggregate signal forming. The second base station is connected on the output side to the device for aggregate signal forming via a converting device which forms the second input signal from the output signal of the second base station.
