Notice of Retraction

After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE's Publication Principles.

We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.

The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.

Multiple-input multiple-output (MIMO) technology can be used in orthogonal frequency division multiplexing (OFDM) systems to improve communication quality and capacity. In this paper, we develop a blind channel estimation method based on a subspace approach for MIMO-OFDM systems. The proposed method obtains accurate channel estimation by utilizing a non-redundant linear precoder at the transmitter and it is insensitive to the overestimates of the channel order. Our method can be applied for MIMO systems with any number of transmitter or receiver antennas. The numerical results are provided to illustrate the effectiveness of the proposed blind channel estimation method.
