New test-bed for evaluation of antenna and system performance for MIMO systems

A new testbed specifically designed for evaluation and measurement of MIMO systems is presented. A flexible and reconfigurable system was implemented, where some system parameters such as sampling frequency and power gain are selectable via software. Also multiple antenna configurations are considered. A user interface was developed in order to simplify testing of algorithm. Thus, the user does not need to design the MIMO scheme or algorithm considering real-time constrains or requirements of the specific platform. On the other hand, real implementation effects and realistic scenarios are included in the system, which allows a more complete study of algorithms. An example with a conventional MIMO algorithm was performed in order to validate the implemented testbed.
