Abstract:Real-time spectrum analyzer can real-timely measure the communication signals. CCDF, which can measure multi-carrier signals very effectively, is one of the important technologies of real-time spectrum analyzer. What’s more, it is widely applied to the wireless signal measurement in 2G and 3G. This paper introduced the main software frame of real-time spectrum analyzer, and it focuses on the principle and processing flow of CCDF. The computer simulation，which bases on the background of OFDM, demonstrates the effectivity of CCDF.
