基于RapidIO的宽带实时频谱分析
Wideband Real-Time Spectrum Analyzer Based on RapidIO
摘要
Abstract
Real-time spectrum analyzer (RTSA) is an important tool of wideband signal detecting and analysis, which is widely studied because of the complex realization. A novel implementation technique of wideband RTSA system is proposed. Two key techniques are expatiated: the technique of a real-time data buffer based on RapidlO can solve the problem of high speed data transfer and mass data buffer storage, the design of signal processor based on pipelining can realize high accuracy and real-time spectrum analysis in the condition of limited hardware resource and processing capacity. The system can realize the capacity of analyzing bandwidth 80 MHz and acquiring data storage 512 MB. And the main performance is close to the advanced level abroad. The system is successfully used in some radar and communication equipments.关键词
