Abstract
In this paper the feasibility of a MIMO OFDM channel tracking algorithm when applied to measured MIMO channels is studied. A time domain channel estimation and tracking based on Kalman filtering is employed while the equalization is performed in frequency domain. Our simulations based on measured MIMO channels show that reliable channel estimation can be performed under realistic conditions. Moreover, some theoretical assumptions are shown to be fulfilled in practice.
