Overview: This paper addresses the problem of channel estimation for Multiple-Input Multiple-Output OFDM systems for mobile users. Radio spectrum is a scarce resource in wireless communication. A very high spectral efficiency in terms of bits/s/Hz may be achieved by employing multiple transmitters and receivers in both ends of the link. Such systems can be modeled using Multiple-Input Multiple-Output (MIMO) system model. High capacity is obtained by exploiting different sources of diversity such as rich scattering envi-ronment. Multicarrier systems, including orthogonal frequency division multiplexing (OFDM) systems play an important role in future be-yond 3G wireless communication services.
