Patent ID: 6996378

Claim:
A transmitter for a plurality of carriers of a broad-band transmitting spectrum, wherein a plurality of carrier-specific baseband input signals are repsectively associated with the plurality of carriers, the transmitter comprising: a broad-band power amplifier encompassing the plurality of carriers and amplifying an input signal into a more powerful output signal; a decoupler for forming a measuring signal from the output signal received from the power amplifier; an adaptation unit for, while the transmitter is in operation, dynamically comparing the plurality of carrier-specific baseband input signals to a respective plurality of carrier-specific measuring signals and thereafter dynamically forming a respective plurality for carrier-specific correction signals, wherein the plurality of carrier-specific measuring signals are derived from the measuring signal and relate to indermodulation frequencies in the transmitter; and a predistortion unit formed of a plurality of carrier-specific predistortion units which respectively, while the transmitter is in operation, dynamically predistort the plurality of carrier-specific baseband input signals corresponding to respective setpoint selections of the respective plurality of carrier-specific correction signals, wherein the predistorted plurality if carrier-specific baseband input signals are subsequently merged to form the input signal.
