RADIO TRANSCEIVER ARRANGEMENT AND METHOD

Abstract:

A method for performing transmission and reception of signals in a radio transceiver arrangement includes creating a first analogue signal to be transmitted based on a digitally predistorted digital input signal and converting a second analogue signal into a digital output signal. The second analogue signal is a combination of a received signal and a transmitter observation signal. The received signal is based on a radio signal received by the radio transceiver arrangement. The transmitter observation signal is based on a tapped signal of the first analogue signal. The digital predistortion of the digital input signal is adapted based on the part of the output digital signal that corresponds to the transmitter observation signal.
