A 3D Indoor Positioning Method of Wireless Network with Single Base Station in Multipath Environment

Abstract: The proliferation of indoor location-based services has increased the demand of indoor positioning technology. Severe multipath and coherence effects are the difference between signal propagation indoors and outdoors. Most existing indoor localization methods build their models in 2-dimensional space and try to avoid the influence of multipath. We propose a method to realize 3-dimensional indoor positioning with single base station by using multipath channel. The angles of multipath coherent signals are estima… Show more

“…Notably, this strategy is effective even in scenarios with insufficient anchor nodes. A similar approach, as presented in [14], leverages multipath channels, with multipleinput multiple-output (MIMO) antennas estimating the angles of multipath coherent signals, and OFDM signals handling delay estimation. By integrating MIMO and OFDM technologies within a wireless communication system, an array antenna is employed to estimate the AoA of multipath signals.…”

“…The significant inter-element isolation contributes to the attainment of enhanced throughput in the MIMO antenna system, hence resulting in improved communication efficiency [31]. MIMO antennas have the potential to provide augmented channel capacity and improved connection dependability by using multipath propagation methods [32]. One of the primary challenges faced by antenna designers is achieving strong interelement isolation in MIMO antennas, particularly in densely packed device environments.…”
