A Decomposition Method for MIMO OTA Performance Evaluation
Diagnosis and troubleshooting are critical to efficiently detecting the imperfections and improving the radio frequency designs for wireless systems in research and development stage. For achieving these, this paper proposes a decomposition method for the measurement of multi-input multi-output (MIMO) devices' over-the-air (OTA) performance. By using the proposed method, the antenna active envelope correlation coefficient, the radiated sensitivity of each receiver, the total isotropic sensitivity, the self-interference, and the desensitization can all be achieved separately, and in OTA working mode. In consideration of the MIMO system's complex array antennas and radio frequency receivers, the parameters obtained by this decomposition method are significant for discovering the imperfections, for debugging, and for improving the design of the devices. It is a valuable tool to raise the debugging efficiency of MIMO systems.
