摘要

误差矢量大小(Error vector magnitude, EVM)作为无线通信系统性能的一种度量，得到了广泛的应用。研究了卫星数字波束形成(DBF)多波束相控阵天线系统的幅值误差和相位误差对EVM的影响。推导了阵列通道幅相误差EVM的解析表达式，并通过计算机仿真进行了验证。

EVM performance evaluation of array channels' amplitude and phase errors for DBF phased array antennas

Error vector magnitude (EVM) is extensively applied as a measure of wireless communication systems' performance. In this paper, the effects of amplitude and phase errors for satellite digital beam-forming (DBF) multi-beam phased array antenna systems on EVM are investigated. The analytic expression for EVM about array channels' amplitude and phase errors is derived and verified by computer simulation.
