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. Multiple-Input Multiple-Output (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.
