| 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. |
