| 摘 要： | 本方案针对无线频谱监测接收机在常规监测中由于扫描速度慢,分辨率低,从而造成信号截获概率低的问题,在总结和分析不同频谱扫描方式特点的基础上,基于软件多线程协调工作的思想,在相互衔接的调谐步进点上设计了一种基于多DSP并行处理的FFT步进扫描方案,发挥其在高分辨率频谱处理上的优势,便于让用户在常规监测时尽可能地发现突发的瞬...

| Abstract: | Radio spectrum monitoring receiver demands for high spectrum resolution and fast spectrum scanning speed.On the basic of summarizing and analyzing the characteristics of different spectrum scanning implementation schemes,we propose a realistic FFT step spectrum scanning scheme based on software control multi-DSP parallel processing.And in the framework of multi-threaded communication,we realize the function of high spectrum resolution and fast scanning speed for broadband spectrum in engineering.The experimental results which can reach a spectrum scanning speed of 4.13GHz/s under condition of resolution bandwidth of 2.3kHz show that this design scheme is effective. |
