Abstract EN
Over-the-air (OTA) throughput tests of wireless Multiple-Input Multiple-Output (MIMO) devices are an important tool for network operators and manufacturers.
The user equipment (UE) is placed in an anechoic chamber and a random fading process is emulated by a base-station emulator (BSE).
The antenna characteristic of the UE is taken into account by sampling the sphere around the UE with the BSE test antenna at a large number of positions.
For low-variance throughput results, long measurement intervals over many fading realizations are required, leading to long and expensive measurement periods in an anechoic chamber.
To speed up the OTA test, we analyze the Decomposition Method (DM).
The DM splits the throughput measurement into two parts: (1) a receiver algorithm performance tests taking the fading process into account and (2) an antenna performance test without fading process emulation.
Both results are combined into a single throughput estimate.
The DM allows for a measurement time reduction of more than one order of magnitude.
We provide an analytic and numerical analysis as well as measurements.
Our detailed results show the validity of the DM in all practical settings.
