Robust Computation of Error Vector Magnitude for Wireless Standards [PDF]
IEEE Transactions on Communications, 2013 The modulation accuracy described by an error vector magnitude is a critical parameter in modern communication systems — defined originally as a performance metric for transmitters but now also used in receiver design and for more general signal analysis.

Evaluation of error vector magnitude due to combined IQ imbalances and phase noise [PDF]
IET Circuits, Devices and Systems, 2014 Novel closed form expressions for the error vector magnitude (EVM) are presented. The expressions combine the in‐phase quadrature (IQ) amplitude and phase imbalances and the DC offsets along with the phase noise. Both the Gaussian and the Tikhonov probability density functions are utilised for the oscillator phase noise distribution.

Gain, Phase Imbalance, and Phase Noise Effects on Error Vector Magnitude
IEEE Transactions on Vehicular Technology, 2004 The error vector magnitude (EVM) is extensively applied as a measure of communication systems' performance. In this paper, the effects of gain, phase imbalance, and phase noise on EVM are examined. The work is focused on single-carrier, linear, and memoryless modulated signals, such as phase-shift keying and quadrature amplitude modulation (QAM).

Error Vector Magnitude Analysis in Generalized Fading With Co-Channel Interference [PDF]
IEEE Transactions on Communications, 2018 In this paper, we derive the data-aided Error Vector Magnitude (EVM) in an interference limited system when both the desired signal and interferers experience independent and non identically distributed $κ$-$μ$ shadowed fading. Then it is analytically shown that the EVM is equal to the square root of number of interferers when the desired signal and ...

Metrology of Optical Communication Systems Using Error Vector Magnitude
Journal of Applied Mathematics and Physics, 2021 Error vector magnitude (EVM) as a performance metric for M-ary quadrature amplitude modulation (QAM) formats in optical coherent systems is presented. It is shown that the calibrated BER, which would otherwise be under-estimated without the correction factor, can reliably monitor the performance of optical coherent systems near the target BER of 10?3 ...
