چکیده
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 developed in the framework of SK Telecom. The frame work is based on IEEE standard of 802.16e adopting MIMO-OFDM. To evaluate the performance, MIMO system verification software tool is also developed and used for off-line performance evaluation. The proposed SDR-based MIMO testbed and verification software tool can be used as efficient tool for channel modeling, capacity of closedloop MIMO capacity verification and etc. The performance of the system is verified by using data generated via METRA channel simulator.
