Orthogonal frequency division multiplexing (OFDM) is a multi-carrier block modulation scheme suitable for wireless communication. OFDM has attracted a lot attention in broadband wireless systems. The use of group selected Adaptive arrays signals processing technology at both transmitter and receiver i.e. MIMO system, with OFDM can be combined to further improve the system performance. But they are relatively characterized by higher implementation complexity than simple selection diversity. It is the simplest way to realize MIMO/OFDM system but the performance improvement of this form of diversity is limited. In MIMO/OFDM system, the CSI is an important factor to impact the system capacity and should be small to improve the system efficiency. In this paper, the two techniques spatial diversity and group selected arrays signal processing are combined for MIMO/OFDM system with imperfect CSI and simulation result shows that system has significant performance improvements over the conventional array based OFDM system over frequency selective multipath fading channels.

Keywords: Channel state information (CSI); MIMO/OFDM; group selected arrays
