A New EVM Calculation Method for Broadband Modulated Signals and Simulation

摘要：

To characterize the quality of wireless telecommuni- cations system more efficiently and integrally, it is necessary to use error vector magnitude (EVM) to be the figure of merit. We describe a typical EVM normalization, and deduce its calculation process. We also have simulated EVM of various modulation types specified by the IEEE 802.11aTM-1999 standard from a given average symbol power based on the basic equation, and compared with the corresponding bit error rate (BER).
