Abstract: A transmitter for a plurality of carriers of a broad-band transmitting spectrum which contains a broad-band power amplifier encompassing the carriers for amplifying an input signal into a more powerful output signal, wherein a measuring signal is formed from the output signal with the aid of a decoupler. The transmitter further contains an adaptation unit for comparing the input signals to the measuring signals and for thereafter forming a correction signal. A predistortion of the input signal is performed in a predistortion unit in the transmitter corresponding to the setpoint selections of the correction signal.

Abstract: When a mobile station first initiates a connection, the mobile station is synchronized on the basis of an evaluation of an organization channel in the mobile radio network. The mobile station transmits, in a frequency band of a home base station and to the home base station a message that contains a mobile-station-specific first identifier. The message is received and evaluated by the home base station. If the first identifier matches a second identifier registered for the home base station, a connection is set up between the mobile station and the home base station.
