Joint Angle And Delay Estimation (Jade) By Partial Relaxation
Ahmad Bazzi, Dirk T. M. Slock · 2019
This paper addresses the Joint Angle and Delay estimation problem of a received multi-carrier frame through multiple antennas. In particular, each source is parameterized through its complex gain, Time-of-arrival (ToA) and Angle-of-arrival (AoA). We develop three novel JADE methods in a partially relaxed model, where one relaxes the interference zone, while focusing on a certain direction at a given time. Computer simulations are given with comparison to the Cramér-Rao Bound.
