Aerogel antennas communications study using error vector magnitude measurements [PDF]

open access: yes2014 IEEE Antennas and Propagation Society International Symposium (APSURSI), 2014
This presentation discusses an aerogel antennas communication study using error vector magnitude (EVM) measurements. The study was performed using 2x4 element polyimide (PI) aerogel-based phased arrays designed for operation at 5 GHz as transmit (Tx) and receive (Rx) antennas separated by a line of sight (LOS) distance of 8.5 meters. The results of the

Error Vector Magnitude Analysis of Fading SIMO Channels Relying on MRC Reception [PDF]

open access: yesIEEE 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.

Metrology of Optical Communication Systems Using Error Vector Magnitude

open access: yesJournal 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 ...

Error Vector Magnitude Analysis in Generalized Fading With Co-Channel Interference [PDF]

open access: yesIEEE 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 $ $-$ $ 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 ...

Broadband Measurement of Error Vector Magnitude for Microwave Vector Signal Generators Using a Vector Network Analyzer

open access: yesIEEE 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 ...

Broadband Error Vector Magnitude Characterization of a GaN Power Amplifier using a Vector Network Analyzer

open access: yes2020 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 ...

Robust Computation of Error Vector Magnitude for Wireless Standards [PDF]

open access: yesIEEE 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.
