Abstract: The inventive concept relates to a communication device comprising a DPD processor configured to output a plurality of pre-distorted signals by pre-distorting each of a plurality of input signals using an extracted feedback signal, a first signal combiner configured to combine a plurality of feedback signals corresponding to the plurality of pre-distorted signals and output a combined feedback signal, an analog-to-digital converter configured to convert the combined feedback signal into a digital signal and output a digital-converted combined feedback signal and a signal extractor configured to extract the digital-converted combined feedback signal and output the extracted feedback signal.
