Abstract :
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 give the definition of EVM and do some more improvement by describing a typical normalization. We also have simulated EVM for various distortion and various modulation types for a given average symbol power from the basic equation, compared with the corresponding bit error rate (BER).
