A Technique for Imprving the Algorithm of Wireless Signal Modulation Analysis
Wi-Fi signal modulation analysis technology is a test and analysis technology that performs high-precision demodulation of Wi-Fi signals,tests the Error Vector Magnitude(EVM)of the signal,and finally shows the modulation characteristics of the signal.In order to meet the test requirements of signal quality during the transmission and transmission of Wi-Fi devices under test,this technology provides an important detection method for fault diagnosis and factory testing of Wi-Fi related devices.In this paper,the phase tracking correction technology and high-precision channel estimation technology are proposed to improve the accuracy of the signal modulation analysis.
