ISSPIT 2016, 16th International Symposium on Signal Processing and Information Technology, 12-14 December 2016, Limassol, Cyprus
A novel approach entitled "Joint Angle and Delay Estimator and Detector", or simply JADED, is presented. This approach allows simultaneous estimation of number of
coherent/non-coherent sources and joint estimation of the angles and times of arrival of each source. The system is composed of a Uniform Linear Array (ULA) receiving known OFDM symbols from a user in an indoor environment, which is rich in multipath. Therefore, the objective is to apply the JADED approach to this scenario, which allows extraction of the Line-of-Sight component based on the first arriving path. The first method, called JADEDRIP, makes use of the Rotational Invariance Properties (RIP) f ULAs and OFDM symbols, detects the number of multipath components, and estimates the angles and times of arrival of each path by performing a 2D search. The second method is a Computationally Efficient Single Snapshot (CESS) version of
the JADED-RIP, i.e. it requires a 1D search followed by a least squares fit, and can only be used when a single OFDM symbol is available. Future insights are given in the Conclusions section.
