Abstract :
We present early results from a 4times4 2.4 GHz ISM band multiple-input multiple-output (MIMO) testbed developed at the University of Newcastle for over-the-air evaluation of MIMO algorithms. To provide maximum flexibility for development of 3 GPP Long Term Evolution (LTE) algorithms, the testbed is designed around a field-programmable gate array (FPGA). The testbed features a simple GUI interface for testbed control as well as a MATLAB interface allowing real channel measurements to be used in algorithm development and evaluation. These features are illustrated here with experimental results from the implementation of Alamouti Space-Time Coding with 64-QAM.
