Space-time coding transmit diversity impairs the system's interference suppression ability because each transmitter generates multiple signals that appear independent to the receive antennas. In this paper, we propose a Multi-Input-Multi-Output (MIMO) MMSE spatial filtering based adaptive antenna arrays method to suppress the co-channel interference (CCI) in space-time coded systems. It is shown that the proposed method can effectively suppress CCI while preserving the space-time structure, thereby, significantly improving the system's interference suppression ability without significant performance degradation.
