The present disclosure provides a method for measuring an amount of interference from an antenna, the method comprising the operations of: receiving at least on reference symbol; calculating a reference symbol NI, which is the antenna-related noise interference (NI) in the at least one reference symbol, on the basis of the at least one reference symbol; receiving at least one data symbol; calculating a data symbol NI, which is the antenna-related NI in the data symbol, on the basis of the at least one data symbol; calculating an NI ratio of the antenna which is the ratio of the data symbol NI relative to the reference symbol NI; and determining an antenna weight of the antenna on the basis of the NI ratio.

Method and apparatus for measuring interference amount

According to an embodiment of the present invention, a method for combining reception signals of a reception device in a wireless communication system comprises the steps of: determining N (here, N is a natural number) number of symbols for performing symbol combining with respect to reception signals; symbol-combining the reception signals for L (here, L is a natural number) number of times according to the determination result; and energy-combining each group of the L number of reception signals for which the symbol combining has been performed. The present research has been performed by receiving support from 'Giga KOREA project' of the Ministry of Science, ICT, and Future Planning.

Method and device for combining reception signals in wireless communication system

A method of an electronic device is provided. The method includes receiving signals from adjacent base stations comprising a first base station and a second base station, respectively, detecting a first synchronization signal and a second synchronization signal for the first base station among the received signals, estimating a first signal corresponding to the detected first synchronization signal and second synchronization signal, eliminating the first signal among the signals received from the adjacent base stations, and detecting a second signal for the second base station.

Apparatus and method for synchronization signal detection

A method for estimating a frequency offset of a reception signal and, more particularly, a signal processing method which can be applied to a receiver modem in a wireless communication system, are provided. The method includes using an absolute value within a specific time area in an inverse discrete fourier transform (IDFT) output of a decorrelation signal between a reception signal and a reference signal, and enabling a highly approximate estimation of a frequency offset through only a single decorrelation test using a characteristic of a predetermined permutation of a signal.
