Abstract :
In this paper, we propose two methods to perform a switching between spatial multiplexing and MIMO diversity in order to improve performances of a 2×2 OFDM-MIMO system. Each method is defined depending on the granularity of the spatial processing. The comparison of BER performances of the two schemes leads to the choice of the sub-carrier based switching processing which gives the most significant improvement.
