Abstract:
In mobile communications the antenna array makes it possible to estimate the path delay, angle of arrival (or angle) and amplitude for the multipath propagation channel. This paper considers the problem of parametric channel estimation by the joint angle and delay estimation (JADE) in a time division system. By exploiting the angle/delay invariance of the channel regardless of the fast faded amplitude variation (i.e., angle/delay is assumed quasi-static). The shift invariance method (JADE-ESPRIT) is chosen for its capacity to pair delay and angle for each path. In this paper, it is shown that the consistency of JADE-ESPRIT for a large enough number of slots guarantees the feasibility of the method for spatially correlated noise. Bounds of the channel MSE are derived when JADE is used.
