【摘要】 误差矢量幅度(EVM,Error Vector Magnitude)是用来测试通信系统的性能的一个关键参数。评估EVM的影响,本文通过实验仿真研究分析了EVM对削峰性能及其峰值流量的影响,给出了在达到峰值速率时所允许的EVM,并给出了不同EVM对性能的影响,同时还给出了一种EVM指标的测量方法。结果表明,EVM指标能的是系统性重要影响因素,对EVM的研究将为提高移动网络性能提供理论基础及实际指导意义。更多还原

【Abstract】 The Error Vector Magnitude( EVM) is a key parameter used to test the performance of a communication system.In order to further evaluate the impact of EVM,this paper analyzed the effect of EVM on peak clipping performance and peak flow through experimental simulation,and gave the EVM allowed when the peak velocity was reached,and gave the effect of different EVM on performance,But also gave a measure of EVM indicators. The results show that the EVM index is an important influencing factor of system performance. The research on EVM will provide theoretical basis and practical guidance for improving the performance of mobile networks.更多还原
