Accuracy Bounds for Array-Based Positioning in Dense Multipath Channels
The accuracy of radio-based positioning systems will Video Interface be limited by multipath interference in realistic application scenarios.This paper derives closed-form expressions for the Cramér⁻Rao lower bound (CRLB) on the achievable time-of-arrival (ToA) and angle-of-arrival (AoA) estimation-error variances, considering the presen
