Abstract

In mobile communications, the multipath space time channel has some fast-varying (faded amplitudes of the paths) and slowly-varying (delays and directions of arrival) features. In this paper we propose to estimate the channel from limited-length training sequences by exploiting these different varying rates without explicitly computing delays and directions of arrival. Therefore, the multi-slot channel estimate is composed of two terms: the slowly-varying space-time bases estimated from L consecutive slots and the fast-varying amplitudes estimated on a slot-by-slot basis. Performance analysis and simulations confirm the expected benefits of the multi-slot approach and demonstrate that for large L the mean square error (MSE) on the channel estimate depends only on the number of fast-varying parameters.
