Abstract

This paper presents a one-dimensional (1D) estimation of signal parameter via rotational invariance technique (ESPRIT)-based approach, TST-ESPRIT, for jointly estimating the directions of arrival (DOAs) and the propagation delays in a wireless multiray channel. The DOAs and the propagation delays are estimated by the spatial-ESPRIT (S-ESPRIT) and by the temporal-ESPRIT (T-ESPRIT), respectively. Based on the spatial-temporal characteristics of the multiray channel, the proposed approach in a tree structure combines the temporal filtering technique and the spatial beamforming technique along with two T-ESPRITs and one S-ESPRIT. The incoming rays are thus grouped, isolated, and then estimated. At the same time, the pairing of the estimated DOAs and delays are automatically determined. Compared with previous works, the TST-ESPRIT can provide better performance with substantially reduced computational complexity. Some simulations are furnished to justify the proposed algorithm.
