Time-multiplexed AoA Estimation and Ranging
2023 International Conference on Localization and GNSS (ICL-GNSS), 2023 A joint angle-of-arrival (AoA) and ranging estimation scheme for ultra-wideband devices is presented and experimentally evaluated. Instead of using N parallel receive chains, antenna elements are sequentially switched to the receiver, i.e., time-multiplexed.
