According to an embodiment, the electronic device adjusts a gain between a first signal path and a second signal path different from the first signal path, based on the comparator, while the first signal is transmitted to the amplifier through the first signal path. The electronic device obtains a first signal transmitted to the first signal path and a second signal generated based on the first signal and transmitted in the second signal path. The electronic device transmits a third signal for selecting a mode related to the gain as any one mode based on the first signal and the second signal, among a first designated mode for adjusting the gain within the designated range or a second designated mode for adjusting the gain to be less than the designated range.

Communication methods of a base station and a terminal are provided. The communication method of the base station includes receiving feedback information including ray gain information from a terminal, configuring a Radio Frequency (RF) precoder to minimize a Frobenius norm of a total transmit precoder of the base station, and configuring a baseband precoder based on Zero-Forcing (ZF). The communication method of the terminal includes receiving a pilot signal from a base station; estimating a channel of the terminal using the pilot signal; configuring ray gain information based on information of the estimated channel; and feeding back a codebook index corresponding to the ray gain information to the base station.
