Accuracy Bounds for Array-Based Positioning in Dense Multipath Channels
Accuracy Bounds for Array-Based Positioning in Dense Multipath Channels is a scholarly work by Thomas Wilding, published in 2018 in ''Sensors''. The main subjects of the publication include acoustics, multipath propagation, upper and lower bounds, computer science, electronic engineering, Cramér–Rao bound, antenna array, bandwidth, delay spread, indoor positioning system, channel, interference, particle filter, global navigation satellite system, specular reflection, algorithm, and Angle of arrival. The 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 presence of multipath radio channels, and extends these results to position estimation.
