基于Virtex-7 FPGA的2.4G无线信号检测系统的设计与实现

he utilization of 2.4GHz frequency spectrumis free according to the international regulation, so there are interferences among wireless devices which working at 2.4GHz.This paper aims at designing a wireless signal test system of ISM (Industrial Scientific Medical) band and implementing it on the platform of Virtex-7 series FPGA, it can be applied in Wireless Local Area Network(IEEE 802.11b/IEEE 802.11g),Blue Tooth, ZigBee and other fields for the analysis of frequency spectrum and coexistence. The system is mainly made up of four parts: the receptionanddemodulationof 2.4G signal,the phase-locked loop (PLL) frequency synthesizer,the double-path Analog-Digital conversion and the Fast FourierTransformation of base-band signal. Finally anorthogonal signal is used to test and identify the efficiency of the system.
