Abstract :
This paper describes the error vector magnitude (EVM) as it is specified for a GSM EDGE (8-PSK) system and presents a method of its derivation. Simulation results of the algorithm applied to a nonlinear power amplifier are shown, and compared to the data obtained with an alternative commercial implementation. The validity of the current EVM proposal as a system linearity figure of merit is also discussed.
