实时频谱分析仪中CCDF测量功能的实现

The implement of CCDF in real-time spectrum analyzer

实时频谱分析仪可以对通信信号进行实时测试,符合现代通信分析仪的发展趋势。CCDF测量是实时频谱分析仪的关键技术之一,对于测量多载波信号非常有用。它普遍应用在2G和3G无线信号测量上。本文介绍了实时频谱分析仪的总体框架,重点阐述了CCDF测量功能的原理和处理流程。并以OFDM系统(正交频分复用)为应用背景验证了这种算法的有效性。

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 3（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 OFT）M, demonstrates the effectivity of CCDF.
