Abstract: An electronic device may include: a transceiver may include an analog-to-digital converter (ADC) and a digital-to-analog converter (DAC); a coupler connected to the transceiver through a feedback path; at least one memory storing instructions; and at least one communication processor configured to execute the instructions to: provide a digital transmission signal to the transceiver; receive a digital feedback signal from the transceiver; and obtain a reflection coefficient based on the digital transmission signal and the digital feedback signal. The DAC may be configured to convert the digital transmission signal into an analog signal, and the ADC may be configured to convert a signal into a digital signal to obtain the digital feedback signal, based on sampling information controlled according to a resource block size of the digital transmission signal.
