Abstract

This paper presents an interference suppression reception scheme for the multiple input multiple output (MIMO) communication systems using orthogonal space-time block codes (OSTBCs) in strong interference scenario. Based on the noise subspace projection, the maximum likelihood decoding (MLD) for OSTBCs can be achieved by simple linear processing in this scheme. Moreover, the approach to obtain the efficient channel state information (CSI) in strong interference scenario is also included in this proposed scheme. The simulation results are given to verify the interference suppression ability of the proposed scheme. Compared with other suppression scheme, the proposed scheme has better SER performance and is more flexible in practical applications.
