What Is the Error Vector Magnitude?
Error vector magnitude (EVM) refers to the difference between the theoretical waveform and the actual received waveform. It is the root mean square value of the ratio of the average error vector signal power to the average reference signal power. Generally GSM requirements 6% (RMS ), WCDMA12.5% (RMS).
