Full Description

Scope

This standard provides recommended practices for the determination of uncertainty in the estimation of error vector magnitude (EVM) of a measured digitally modulated wireless communication signal. Such practices include several methods for validating a user’s measurement of a specific reference waveform by comparison to a reference measurement. The methods differ based on the level of rigor desired by the user and the accessibility to timing and waveform recording capabilities of the available hardware. Methods for evaluating measurement uncertainty in EVM are also presented. Some of the methods described here focus on measurements and uncertainties related to the use of laboratory-based measurement equipment such as vector receivers, real-time and equivalent-time sampling oscilloscopes and other types of waveform recorders that have access to the measured waveform. This allows time-alignment and gain normalization of measured waveforms prior to the calculation of EVM. Other methods focus on specialized receivers that report symbols directly. As part of the assessment of the measurement hardware and associated uncertainty analyses, this practice includes a mathematically rigorous method for the determination of EVM.

Purpose

The purpose of this recommended practice is to provide a standardized approach to assess the impact of the receiver hardware performance on a measurement-based estimate of the EVM of a distorted signal. This is done by comparing a user’s measurement to a reference measurement of a specific waveform. The reference measurement is intended to provide a well-characterized estimate of the EVM, to which the user’s measurement and associated uncertainty are compared. In addition to the IEEE 1765 baseline approach to estimating EVM, various example approaches to validating receiver measurements of EVM are provided in this recommended practice.
