Abstract: 
over-the-air (OTA) testing is an industry standard practice for evaluating transceiver performance in wireless devices. For the fifth generation (5G) and beyond 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, multiple-input multiple-output (MIMO) 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 multiprobe anechoic chamber (MPAC) method, the reverberation chamber plus channel emulator (RC+CE) method, and the radiated two-stage (RTS) method, with the aim of providing a useful guideline for developing effective wireless performance testing in future 5G-and-beyond wireless systems.

摘要:空中测试(OTA)是评估无线设备中收发性能的一种行业标准做法。对于第五代(5G)和更高集成度的无线系统,OTA测试可能是能够准确测量收发器性能的唯一可靠方法,可用于设备认证,并为设计验证和优化提供反馈。此外,多入多出(MIMO)技术被广泛用于稳定连接、高吞吐率和低延迟的无线系统中。本文概述了评估OTA MIMO性能的3种主要方法,即多探头法(MPAC)、混响室加信道模拟器(RC+CE)方法和辐射两步法(RTS),目的是为5G及未来无线系统的无线性能测试提供有用指导。
