MIMO technologies with OFDM air interface lead to a very compelling high-speed data transmission for future wireless systems. Since performance verification of MIMO system is important, Software Based Radio(SDR)-based MIMO testbed becomes essential to validate the theoretical performance gain. In this paper, we present SDR-based MIMO testbed system(More)
