Method for determining receiving direction of periodic signal containing received signal established in reception antennas, involves determining amplitude and/or phase difference between spectral components of periodic signals

摘要

The method involves determining a two-dimensional spectrum of received signal on reception antennas (1-1-1-N). Each periodic signal spectrum is determined within two-dimensional spectrums of received signal on two reception antennas. The receiving direction of respective periodic signals is determined by determining the amplitude and/or phase difference between spectral components of respective periodic signals of two receiving antennas. Independent claims are included for the following: (1) device for determining receiving direction periodic signal containing received signal existing in receiving antennas; and (2) computer program product for determining receiving direction periodic signal containing received signal existing in receiving antennas.
