摘要
接收灵敏度是无线通信系统中非常重要的参数之一。然而,虽然无线技术的发展迅速,接收灵敏度的测量却依然使用着传统的基于穷举法的测量方式。这种测量方式依赖固有的系统模型,不但测量效率低,而且由于使用固定步长,测量精度也无法保证。针对传统测量方法的缺陷,本文提出一种不依赖模型,只基于实时测量数据的快速接收灵敏度测量方法,这种方法依靠系统实时的输入和输出数据,在保证测量精度的同时进一步改善测量速度。
In wireless communication systems, receiver sensitivity is one of the most importantparameters. However, even though the wireless technology has got a progress with marvelous rapidity,the traditional exhaustive search is still being used to identify the receiver sensitivity. Such an exhaustivesearch scheme depends on the system model, it is neither efficient, nor accurate due to the fixedstepsize. To solve the problems in traditional method, we introduce a new fast sensitivity measurementmethod, which depends merely on the real-time input and output measurement data of the system. It canfurther speed up the measurement of the receiver sensitivity while satisfying the accuracy requirement.
