APPARATUS AND METHOD FOR SPATIAL FILTERING BY ESTIMATING ANGLE OF DEVIATION FOR LINE OF SIGHT OF USER |
摘要 |
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. |

1. An apparatus for spatial filtering, comprising:
a radio frequency (RF) processor receiving a signal including a transmission frame, transmitted from a first terminal, and RF-processing the received signal; a synchronization processor detecting a synchronization point in time for signal demodulation using a synchronization signal included in the transmission frame of the signal RF-processed by the RF processor; a received signal processor demodulating a user-defined sequence and spatial random jitter beamforming (SRJBF) sequences received after the user-defined sequence when the synchronization processor detects the synchronization point in time; a sequence storage storing the user-defined sequence demodulated by the received signal processor therein; and an angle estimator estimating an angle of deviation between the apparatus and the first terminal based on a reference direction line of the apparatus by using the user-defined sequence stored in the sequence storage and the SRJBF sequences demodulated by the received signal processor. |
