Abstract

is an industry standard practice for evaluating transceiver performance in wireless devices. For the wireless systems with high integration, OTA testing is probably the only reliable method to accurately measure the transceiver performance, suitable for certification as well as for providing feedback for design verification and optimization. Further, technology is extensively applied for stable connection, high throughput rate, and low latency. In this paper, we provide an overview of the three main methods for evaluating the MIMO OTA performance, namely, the method, the method, and the method, with the aim of providing a useful guideline for developing effective in future 5G-and-beyond wireless systems.
