我们分析表征的数据辅助误差矢量幅度（EVM）的性能的单输入多输出（SIMO）通信系统依赖于最大比合并（MRC）具有独立或相关的分支，是不相同的分布。特别地，推导了η-μ衰落和κ-μ阴影衰落信道下EVM的精确闭合形式表达式，并通过仿真验证了这些表达式的正确性。导出的表达式用第四类劳里切拉函数FD（N）（.）表示，其可以容易地计算。此外，我们简化了各种特殊情况下，如独立和同分布的分支，瑞利衰落，Nakagami-m衰落和κ-μ衰落的推导表达式。此外，无线系统的EVM性能的参数研究。
We analytically characterize the data-aided error vector magnitude (EVM) performance of a single-input multiple-output (SIMO) communication system relying on maximal ratio combining (MRC) having either independent or correlated branches that are nonidentically distributed. In particular, exact closed form expressions are derived for the EVM in η-μ fading and κ-μ shadowed fading channels and these expressions are validated by simulations. The derived expressions are expressed in terms of Lauricella's function of the fourth kind FD(N) (.), which can be easily computed. Furthermore, we have simplified the derived expressions for various special cases such as independent and identically distributed branches, Rayleigh fading, Nakagami-m fading, and κ-μ fading. Additionally, a parametric study of the EVM performance of the wireless system is presented.
