“…Despite these advantages, conventional DoA acquisition suffers from a number of challenges. Most DoA estimation techniques rely on an array-based hardware architecture, such as Bartlett algorithm 1–3 , Capon algorithm 4–7 , MUSIC algorithm 8–12 and ESPRIT algorithm 13–17 . Because these techniques require beam synthesis on the receiver side, the channel information is collected by means of synthesizing a composite aperture either mechanically, such as in synthetic aperture radar (SAR) 17–19 , or electronically, such as in phased arrays 20–24 .…”

“…The multiple signal classification (MUSIC) algorithm was created by using MATLAB [29] to determine the direction of indoor incoming signal [30]- [34], where the algorithm has very high resolution and estimation precision and is ideal for circular array antenna topology. Note that the algorithm was implemented to determine the incoming signal direction for the four-, five-, six-, and eight-element circular array antennas by varying the number of incoming signals (2, 3, and 4 signals).…”

“…The direction of incoming signal can be determined by the estimated function of the MUSIC algorithm (see ( 3)) [30]- [34], where () a is the steering vector corresponding to incoming signals,…”

“…Many techniques have been proposed for measuring DOAs, such as MUSIC, ESPRIT and SAGE [16], [17]. For example, a linear array is utilized in [18] with the alternate elements orthogonally polarized, such that the estimation of azimuth/elevation angles can be conducted by only one-dimensional search in the MUSIC algorithm.…”
