Research on High-Precision Indoor Positioning Algorithm Based on Enhanced MUSIC Spatial Smoothing Technique

In metal-dense indoor environments (such as maglev maintenance workshops), multipath reflections generate coherent signals that cause rank deficiency in the array covariance matrix, leading to severe angle-of-arrival (AOA) estimation bias and false peaks in the conventional MUSIC algorithm. To address this issue, this...
