The Error Vector Magnitude (EVM) performance in LTE Downlink
2019 Cross Strait Quad-Regional Radio Science and Wireless Technology Conference (CSQRWC), 2019The Error Vector Magnitude (EVM) is a useful magnitude in the development and design process to indicate the entire signal quality. The post-equalized signal has better performance than pre-equalized signal due to its robustness against noise during channel equalization processing under ideal and interpolation channel estimation.

SLIC EVM — Error vector magnitude without demodulation
2017 89th ARFTG Microwave Measurement Conference (ARFTG), 2017We present a method for measuring a communication signal's inband error caused by a non-ideal device under test (DUT). In contrast to the established error vector magnitude (EVM), we do not demodulate the data symbols. Rather, we subtract linearly correlated (SLIC) parts from the DUT output and analyze the power spectral density of the remaining error ...

Importance of Preserving Correlations in Error-Vector-Magnitude Uncertainty
2018 91st ARFTG Microwave Measurement Conference (ARFTG), 2018Correlations between measurement records, e.g., frequencies or time records, are an important consideration in the uncertainty analysis of high-frequency electronic systems. To study the importance of preserving correlations, we introduce a method to scramble the correlations of a correlated uncertainty analysis and develop a software tool to do this ...

A Measurement-Referenced Error Vector Magnitude for Counterfeit Cellular Device Detection
2023 101st ARFTG Microwave Measurement Conference (ARFTG), 2023Standard formulations of error vector magnitude compare a wireless device's symbol constellation to an ideal reference constellation. In this work, we utilize the residual error vector magnitude, which uses measurements of a wireless device to define a ...

Error vector magnitude to SNR conversion for nondata-aided receivers
IEEE Transactions on Wireless Communications, 2009Error vector magnitude (EVM) is one of the widely accepted figure of merits used to evaluate the quality of communication systems. In the literature, EVM has been related to signal-to-noise ratio (SNR) for data-aided receivers, where preamble sequences or pilots are used to measure the EVM, or under the assumption of high SNR values.

V-band six-port quadrature demodulator : Error Vector Magnitude analysis
Global Symposium on Millimeter-Waves (GSMM), 2015Direct conversion quadrature demodulator analysis based on recently fabricated V-band six-port circuit operating over 60 GHz band is presented in this paper. In order to obtain realistic system simulation results, the computer model of the six-port demodulator is implemented using Advanced Design System (ADS) software and S-parameter measurements of ...

Test setup for error vector magnitude measurement on WLAN transceivers
2012 19th IEEE International Conference on Electronics, Circuits, and Systems (ICECS 2012), 2012This paper presents a measurement system and experimental examples of error vector magnitude measurements on a wireless local area network receiver under several radio frequency impairments, with emphasis to local oscillator phase noise. An algorithm that cancels the phase and frequency carrier synchronization error is presented.

On full-duplex link performance under consideration of error vector magnitude
2014 IEEE Wireless Communications and Networking Conference (WCNC), 2014The effect of Error Vector Magnitude (EVM) to the performance of a full-duplex bi-directional link is studied. EVM is modelled as independent Gaussian noise, which is sent together with the original signal by the transmitter. A simplified self-interference cancellation model at the full-duplex receiver is considered. It suppresses the self-interference
