Application of Kalman Filtering Approach on Signal Angle-of-Arrival Estimates
2023 31st Signal Processing and Communications Applications Conference (SIU), 2023 This study focuses on modifying the Kalman Filtering (KF) approach, whose measurement noise suppression capability had been proven many times, especially in multidimensional positioning problems, to serve one-dimensional signal angle-of-arrival (AoA) measurements, and examining the overall AoA estimation performance.
