Abstract: The disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). A method of operating an electronic device in a wireless communication system is provided. The method includes inputting training signals into a first loopback route and a second loopback route, determining a loopback gain and a loopback phase, based on a first training signal passing through the first loopback route and a second training signal passing through the second loopback route, determining a frequency domain compensation filter, based on the loopback gain and the loopback phase, determining an FIR filter and a DC offset, based on the frequency domain compensation filter, and compensating for a transmission signal and a reception signal, based on the FIR filter and the DC offset.

Abstract: Provided are a radio frequency (RF) signal transmission apparatus and a control method of the RF signal transmission apparatus, in which a local oscillator (LO) leakage signal may be suppressed. The RF signal transmission apparatus may perform beamforming to form a beam based on a plurality of RF signals generated in a plurality of transmission chains, measure magnitude of an LO leakage signal of the beam formed by performing beamforming, and generate an LO leakage suppression signal based on the magnitude of the LO leakage signal.
