摘要：
This paper focuses on the problem of angular spread (AS) estimation at the base station in a macro-cellular system when a Line-Of-Sight (LOS) component is potentially present. We will limit our study to low-complexity methods prone to practical implementation. The paper demonstrates the limitations of the well-known low complexity AS estimation method, Spread Root-MUSIC. As supported by simulations, it introduces a lower complexity "Look-Up Table" (LUT) based approach that compares advantageously with Spread Root-MUSIC from the point of view of complexity and performance.
