Estimation of Obtainable Data-Rates in an Over-The-Air mm-Wave MIMO Testbed

In the era of 5G and the forthcoming 6G technology, the demand for advanced communication systems has surged, driving the need for innovative testbeds. These testbeds are vital for the rapid development of hardware and algorithms. Estimation of the capacity potential of mm-wave transceiver arrays is essential to maximise performance. Moreover, an efficient and effective estimation method is indispensable to ensure swift iterations during the development process. Such rapid experimentation is essential for identifying and addressing potential bottlenecks. Here we demonstrate a method based on cross correlation to estimate data-rates in a mm-wave testbed using Over-The-Air measurements only. The method is tested using the Chalmers mm-wave testbed MATE at 29.4 GHz.
