Abstract:
A method for receiving a signal by using M multiple beams in a multi-antenna system including N antenna elements, is provided in and embodiment of the present application. The method includes setting, by M beams, a beam direction for the M beams and a modulation frequency for frequency modulation of a beam response and generating the M beams according to the beam direction and the modulation frequency set by the beams. M beam responses are generated for a receiving signal by using the generated M beams and the generated M beam responses are frequency modulated by using the modulation frequency set by the beams. The frequency-modulated M beam responses are band-pass filtered so as to separate the M beam responses and the separated M beam responses are respectively demodulated.
