发明名称 METHOD AND DEVICE FOR POWER AMPLIFIER WITH HIGH ACCURACY OF AN OUTPUT SIGNAL
摘要 The invention relates to a method for improving the output signal accuracy of a transmitter with a forward branch for converting an input signal into a signal for transmission. The forward branch comprises an adaptation unit ( 103 ) for applying a predistortion to the input signal and a power amplifier ( 106 ). The transmitter has a first feedback branch ( 110 ), the first feedback branch ( 110 ) generating a feedback signal from the signal for transmission, said feedback signal being fed back to the adaptation unit ( 103 ), and the predistortion applied to the input signal is determined according to the feedback signal. The method comprises the steps of: measuring the output power of said signal for transmission in a second feedback branch ( 201 ) and adjusting the predistortion according to said measurement of the output power. A transmitter and a computer program product adapted to the method are also described.
