Abstract
An electronic device is provided. The electronic device includes a digital pre-distortion (DPD), a digital-to-analog converter (DAC), a power amplifier (PA), a first coupler obtaining a feedback signal from an output of the power amplifier, a circulator obtaining a reverse signal in which the output of the power amplifier is reflected, a transmission filter, a second coupler obtaining a filter-feedback signal from an output of the transmission filter, an antenna, an analog-to-digital converter (ADC) converting a composite signal including the feedback signal, the filter-feedback signal, and the reverse signal into a digital composite signal, a separation circuit, and a pulse inter-modulation cancellation (PIMC) circuit in which the separation circuit, based on the digital composite signal and an input signal of the DPD, obtains a digital signal of the feedback signal, a digital signal of the filter-feedback signal, and a digital signal of the reverse signal.
