This paper proposes an advanced OFDM-MIMO reconfigurable architecture that uses an adaptive switching algorithm between diversity and spatial multiplexing. The transmitter blocs' specifications such as the MIMO technique and the modulation scheme are adjusted according to the channel state, which gives a practical cognitive radio strategy. The system cost- efficiency is performed by the application of the Software Defined Radio (SDR) technology. Based on the Demmel condition number criterion, an indicator bit exchange between the transmitter and the receiver allows selecting the adapted MIMO configuration and improving the whole system performances.
