Abstract
An apparatus for spatial filtering receives a signal transmitted from a first terminal and detects a synchronization start point in time from a transmission frame included in the signal. The apparatus for spatial filtering demodulates a user-defined sequence included in the transmission frame and the at least one SRJBF sequence when the synchronization start point in time is detected, and then estimates a relative angle based on the demodulated user-defined sequence and SRJBF sequence.
