About

Dr. Benyuan Liu is a leading researcher in wireless communications and localization, with a particular focus on angle-of-arrival (AOA) estimation and signal processing. His foundational work, "Theory underlying measurement of AOA with a rotating directional antenna" (2013, 10 citations), addresses a critical gap in wireless localization: the precise theoretical relationship between received signal strength (RSS) from a rotating directional antenna and the true AOA of a target signal. This contribution provides a rigorous mathematical framework that enables more accurate and reliable localization in environments where GPS is unavailable, such as indoor or urban canyons. Dr. Liu’s research has significant implications for the Internet of Things (IoT), autonomous navigation, and emergency response systems. By clarifying the underlying theory of AOA measurement, his work empowers engineers to design more efficient localization algorithms and hardware. Though early in its citation history, this paper is poised to become a cornerstone reference for researchers and practitioners seeking to enhance wireless positioning accuracy through directional antennas. Dr. Liu’s dedication to bridging theory and application marks him as a rising authority in the field.
