The maximum likelihood (ML) estimation for multipath component (MPC) parameters requires high computational complexity, resulting in low efficiency in channel measurement campaigns. In this paper, a new method, called Fast Reduced-Dimension SAGE (FRDS) algorithm, is proposed to estimate the parameters such as excess delay, power, and angle-of-arrival/departure (AoA/AoD). By sounding channels using...
To characterize multipath spatial propagations in three-dimensional space is critical in wireless channel measurements and modeling. Due to the large number of paths and the correlation among multipath signals, the direction-of-arrival (DoA) estimation for propagation paths is a challenging issue. In this letter, we propose a new multipath DoA estimation scheme, named Multipath DoA Estimation by Rotational...
