摘要
首先介绍了误差矢量幅度(EVM)的定义和计算方法,然后结合通信发射系统的特征,分析、仿真或实测了I/Q不平衡、相位噪声、非线性放大和信道加性高斯白噪声等因素对EVM指标的影响。
This paper firstly introduces the definition and calculation method of error vector magnitude(EVM),then combined with the characteristics of communication transmission system,analyzes,simulates or measures the influence of I/Q imbalance,phase noise,nonlinear amplification and channel additive Gaussian white noise on the EVM index one by one.
