Abstract

In this work, we verify experimentally the consistency of EVM across modulation types of orthogonal frequency-division multiplexed (OFDM) signals in two dedicated lab setups. We compared EVMs obtained for different modulation types both in an idealized distortion-free and a realistic multipath environment.
