Abstract: The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a higher data transmission rate than 4th generation (4G) communication systems such as long term evolution (LTE). In a wireless communication system, a transmission apparatus comprises at least one antenna port for transmitting/receiving a signal, an analogue filter for selecting the frequency of the signal, and a voltage standing wave ratio (VSWR) detection unit for measuring the VSWR of the antenna port, wherein the VSWR detection unit is configured to detect both a forward signal and a reverse signal for an input terminal of the analogue filter, to determine the respective power values of a forward signal and a reverse signal for an output terminal of the analogue filter by applying characteristic parameters of the analogue filter to the detected forward signal and reverse signal, and to determine the VSWR of the antenna port on the basis of the respective power values of the forward signal and the reverse signal for the output terminal of the analogue filter.

Abstract: A method of extracting an Integrated Circuit (IC) current is provided. The method includes generating a transfer function value by using a voltage measured in a node nearest an input terminal of the IC, substituting the generated transfer function value for a reverse fast Fourier transform function, so as to extract the IC voltage, and extracting the IC current from the extracted IC voltage through a simulation in a time domain.
