摘要: We propose a practical, simple and hardware friendly, yet novel efficient, angle of arrival (AoA) estimation system. Our intuitive, two-phases cross-correlation-based system requires switched beam antenna array with single radio frequency circuitry, which is used to collect an omni-directional reference signal using element the in first phase. applies energy detection on collected decide presence or absence transmitted signal. In second phase, steers main scan angular region interest. The from each cross correlated determine received combined practicality high efficiency our demonstrated through performance complexity comparisons one literature’s best performing multiple classification (MUSIC) algorithm. proposed AoA has negligible root mean square error at noise ratio level greater than −16 dB, very comparable MUSIC.
