Abstract :
This paper addresses the problem of channel estimation and tracking for space-time block coding. Channel tracking performance is investigated using several recursive algorithms. In the simulations it is shown that different channel tracking procedures can be used in several scenarios. As a performance criterion the orthogonality property of the decoding matrix is considered. A realistic channel model developed in COST 207 project is used in our examples.
