Traceable measurement of Error Vector Magnitude (EVM) in WCDMA signals

2007 International Waveform Diversity and Design Conference, 2007
This is the first report of a methodology to provide national standards traceability for EVM measurement of WCDMA RF sources using waveform metrology techniques. The method uses sampling oscilloscopes or real-time digital oscilloscopes. Preliminary results indicate that the rms uncertainty of the modulation waveform, at 95% confidence, is less than 0.3

Evaluation of error vector magnitude due to combined IQ imbalances and phase noise

open access: yesIET Circuits, Devices and Systems, 2014
Novel closed form expressions for the Error Vector Magnitude (EVM) are presented. The expressions combine IQ amplitude and phase imbalances, DC offsets along with phase noise.

Error Vector Magnitude (EVM) Measurements for GSM/EDGE Applications Revised under Production Conditions

2005 IEEE International Symposium on Circuits and Systems, 2005
A main concern in the testing of systems fulfilling the enhanced general packet radio service (EGPRS) requirements is the proper measurement of the error vector magnitude (EVM) for the implemented 8PSK modulator. However, handsets supporting EGPRS also incorporate a GMSK modulator and hence, in order to reduce computing time on the production tester by

Uncertainty and design budgets applied to error vector magnitude (EVM) for digital modulation systems

61st ARFTG Conference Digest, Spring 2003., 2004
EVM is a key metric for RF components and subsystems in most digital modulation systems. Understanding the way in which different distortion mechanisms contribute to the overall EVM is the key to determining how to construct a system budget for EVM.

THE EFFECT OF RADIO FREQUENCY INTERFACE IMPERFECTIONS ON THE ERROR VECTOR MAGNITUDE (EVM) IN LTE AND 5G SYSTEMS

Proceedings of XVII International Conference Measurement and Control in Complex System (MCCS-2024)
The development of telecommunications proceeds by increasing the speed of information transmission, improving the quality of communication, and providing new services. Modern mobile phones have a transmitter and a receiver located in the same housing. Double frequency conversion is used to transfer the spectrum of signals from the main frequency band ...
