摘要
Abstract
The system design for wireless signal monitoring in wide frequency range is realized in this paper based on the SR digital intermediate frequency reception theory. In this subject,the digital intermediate frequency receiver was achieved. The processed spectrum,signal and monitoring information is uploaded to DSP for demodulation. The modeling simulation in system level was realized by means of Simulink. All the data path modules,including NCO module,FIR filter module and FFT module were realized by the aid of Verilog HDL. The hardware platform was created and the prototype verification was performed through FPGA. The system′s monitoring range of frequency is 500 KHz~6GHz and SNR of output signal is more than 50dB. The system realized the monitoring function of wireless spectrum signal and met the design requirements.关键词
