Title:
ELECTRONIC DEVICE INCLUDING TRANSCEIVER FOR CALIBRATING I/Q IMBALANCE IN MILLIMETER WAVE COMMUNICATION SYSTEM AND METHOD OF OPERATING SAME
Document Type and Number:
WIPO Patent Application WO/2021/010807
Kind Code:
A1
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.
