A1
Abstract:
The present disclosure relates to an apparatus and a method for transmitting a signal using a power amplifier in a wireless communication system. A transceiver in a wireless communication system may comprise: a digital predistorter for distorting an input signal on the basis of a distortion control value; a power amplifier for amplifying a signal outputted from the digital predistorter; an antenna for transmitting a signal outputted from the power amplifier; an echo signal canceller for removing, from a feedback signal obtained at an output terminal of the power amplifier, an echo signal returning to the power amplifier due to the return loss of a path between the power amplifier and the antenna; and a digital predistortion adaptor for determining the distortion control value on the basis of the signal outputted from the echo signal canceller.
