摘要

本文从实际接收机前端缺陷引起的检测退化的角度研究了一种频谱传感技术的评价。针对广泛应用的无线电设备USRP，对四种不同类型的前端采用不同调制格式的两种频谱传感探测器(能量探测器和基于拟合优度的探测器)进行了测试。通过对前端结构及其噪声参数的分析，通过实际实验测量和接收机工作特性评估，验证了该方法的真实检测性能。

Experimental evaluation of the impact of receiver front-end on spectrum sensing

This paper investigates the evaluation of a spectrum sensing technique from the point of view of detection degradation caused by the real receiver front-end imperfections. Two spectrum sensing detectors (energy detector and goodness of fit - based detector) have been tested with various modulation formats for four different types of front-ends in form of daughter-boards for widely used radio device USRP. After analysis of front-end architectures and their noise parameters, the real detection performance has been confirmed by the real experimental measurements and receiver operational characteristics evaluation.
