Abstract

We estimate the position and orientation of the Hidden Node (HN) at the Sensing Node (SN) in a 3D channel environment with only the multi-path Non-Line-of-Sight (NLoS) channel. We estimate the position and orientation of HN using the parameters of Angle-of-Arrival (AoA), Angle-of-Departure (AoD), and Time-Difference-of-Arrival (TDoA) estimated at SN. We introduce how to deal with non-linear equations with exhaustive searching with LS estimation and Generalized Approximate Message Passing (GAMP) with the first-order approximation. We also evaluate Mean Squared Error (MSE) for performance measure and processing time for complexity. Finally, We introduce a ratio of MSE to the processing time to show a trade-off in each scheme, showing that GAMP is superior to the exhaustive search with Least Square (LS).
