The generation and test method of User-defined standard OFDM signal based on graphic wizard

Focusing on the complexity of OFDM(Orthogonal Frequency Division Multiplexing) signal structure and no general OFDM signal generation method and test method being available, and basing on the analysis of the typical OFDM signal physical layer structure, this paper proposes a generation and test method of user-defined standard OFDM signal based on the graphic guide, which has strong universality and convenience for non-standard OFDM signal generation and testing. Then, the vector signal generator and spectrum analyzer are used to test and verify the result, and the importance of time and frequency synchronization to non-standard OFDM signal test is given. This paper provides strong support for development of communication technology.
