The original text was copied without attribution (including appropriate references to the original author(s) and/or paper title) and without permission. <br><br>Due to the nature of this violation, reasonable effort should be made to remove all past references to this paper, and future references should be made to the following article:<br><br>"EVM Calculation for Broadband Modulated Signals"<br> by Michael D. McKinley, Kate A. Remley, Maciej Myslinski, J. Stevenson Kenney, Dominique Schreurs, Bart Nauwelaers,<br>in the Proceedings of the 64th ARFTG Conference, December 2004, pp. 45-52<br><br> <br/> To characterize the quality of wireless telecommunications 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).
