摘要

本文介绍了一种无线局域网接收机在几种射频损伤下误差矢量幅度的测量系统和实验实例，重点介绍了本振相位噪声。提出了一种消除相位载波和频率载波同步误差的算法。在这些损伤的影响下，得到了典型的基带优值图。所描述的方法允许在没有专用矢量分析仪的情况下进行误差矢量幅度的实验计算。

Test setup for error vector magnitude measurement on WLAN transceivers

This paper presents a measurement system and experimental examples of error vector magnitude measurements on a wireless local area network receiver under several radio frequency impairments, with emphasis to local oscillator phase noise. An algorithm that cancels the phase and frequency carrier synchronization error is presented. Typical base band figure of merit are obtained under influence of these impairments. The described method allows the experimental calculation of error vector magnitude without a dedicated vector analyzer.
