ELECTRONIC DEVICE AND OPERATING METHOD OF ELECTRONIC DEVICE

According to an aspect of the inventive concept, an electronic device includes a transmitter including a plurality of antennas, and a communication processor for calculating a total exposure ratio (TER) value of each of the plurality of antennas, wherein the communication processor includes an antenna index buffer for storing a used antenna index, which is an index of one or more used antennas from among the plurality of antennas used in each window, a used power buffer for storing used power of an antenna corresponding to the used antenna index, and a controller configured to calculate the TER value based on the used antenna index, the used power, and an influence matrix.
