Broadband Measurement of Error Vector Magnitude for Microwave Vector Signal Generators Using a Vector Network Analyzer [PDF]
IEEE Transactions on Instrumentation and Measurement, 2022 A frequency-domain method is proposed for the broadband measurement of error vector magnitude (EVM) for vector signal generators (VSGs). The technique is based on frequency-swept narrowband acquisitions performed with a vector network analyzer (VNA) by exploiting a stable (yet unknown) reference signal to obtain phase-repeatable measurements ...

On the error vector magnitude as a performance metric and comparative analysis [PDF]
2006 International Conference on Emerging Technologies, 2006 In this paper, we present the error vector magnitude (EVM) as a a figure of merit for assessing the quality of digitally modulated telecommunication signals. We define EVM for a common industry standard and derive the relationships among EVM, signal to noise ratio (SNR) and bit error rate (BER).

Broadband Error Vector Magnitude Characterization of a GaN Power Amplifier using a Vector Network Analyzer [PDF]
2020 IEEE/MTT-S International Microwave Symposium (IMS), 2020 This work investigates the impact of nonlinear dynamic effects due to charge trapping and other long-memory phenomena on the wideband linearity of power amplifiers (PAs) for 5G communications applications. The proposed method uses the well-known best linear approximation framework (BLA) to estimate the error vector magnitude (EVM) of the amplifier for ...

Error Vector Magnitude Analysis of Fading SIMO Channels Relying on MRC Reception [PDF]
IEEE Transactions on Communications, 2016 We analytically characterize the data-aided error vector magnitude (EVM) performance of a single-input multiple-output (SIMO) communication system relying on maximal ratio combining (MRC) having either independent or correlated branches that are nonidentically distributed.
