| 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 RapidIO 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... |
