Error vector magnitude to SNR conversion for nondata-aided receivers

IEEE Transactions on Wireless Communications, 2009
Error 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.

Test setup for error vector magnitude measurement on WLAN transceivers

2012 19th IEEE International Conference on Electronics, Circuits, and Systems (ICECS 2012), 2012
This 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.

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 as a Performance Measure for Advanced Modulation Formats

IEEE Photonics Technology Letters, 2012
We examine the relation between optical signal-to-noise ratio (OSNR), error vector magnitude (EVM), and bit-error ratio (BER). Theoretical results and numerical simulations are compared to measured values of OSNR, EVM, and BER. We conclude that the EVM is an appropriate metric for optical channels limited by additive white Gaussian noise.

OFDM Error Vector Magnitude Distortion Analysis

IEICE Transactions on Electronics, 2006
We derived explicit formulas for evaluating the error vector magnitude (EVM) from the amplitude distortion (AM-AM) and phase distortion (AM-PM) of power amplifiers (PAs) in orthogonal frequency-division multiplexing (OFDM) systems, such as the IEEE 802.1 1a/g wireless local area networks (WLANs) standards.

Error Vector Magnitude Analysis for OFDM Systems

2006 Fortieth Asilomar Conference on Signals, Systems and Computers, 2006
Error vector magnitude (EVM) is a popular figure-of-merit adopted by various communication standards for evaluating in-band distortions introduced in a communication system. In this paper, we regard EVM as a random variable and investigate its statistical distributions as the result of the following distortion mechanisms: phase noise, amplitude ...

Replacing Error Vector Magnitude Test with RF and Analog BISTs

IEEE Design & Test of Computers, 2011
RF and analog BIST techniques are capable of replacing the traditional error vector magnitude (EVM) test used in production. In a case study, four BISTs detected actual production faults in a commercial, highly integrated WLAN device. In combination with traditional digital testing, the BISTs caught an impressive 100% of EVM failures during production ...
