Modulation Mode and Testing for Radio Frequency of Bluetooth
Qiang Ma · Modern Electronics Technique · 2008
The paper introduces the radio frequency characteristics of bluetooth 1.2 and 2.0 version,analyzes three kinds of digital modulation,two kinds of packet format of the data rate and the constellation graph of the signal,calculates the Freq-Range utilization of Gaussian filter and root-raised cosine filter,explains that different Bluetooth versions possess distinct radio frequency characteristics.According to the time feature of frequency hopping signal of Bluetooth,it forwards out the rapid testing of frequency hopping signal operates with real-time spectrum analyzer.
