Title: Comparison of QPSK and 64QAM EVM for an OFDM WLAN Signal at 2.4 GHz and 4.9 GHz in a Multipath Environment
Published: June 01, 2009
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.
