Universidad de Zaragoza (orcid)0000-0001-5849-5198 Markov mode-multiplexing mode in OFDM outphasing transmitters 2018 Access copy available to the general public Unrestricted Outphasing transmitters have been explored to study the trade-off between linearity and efficiency. The outphasing technique enhances efficiency by operating two amplifiers at lower output amplitudes, using two constant envelope signals. Their major drawback is the inherent sensitivity to gain and phase imbalances between the two amplifier branches. Another important issue is related to the degradation of efficiency, especially in isolated combiners. This paper presents a Statistical Markov-Chain Mode-Multiplexing (MM) transmitter which combines features of the MM and Reverse MM-LINC. Commercial analog devices and a digital platform for signal processing purposes are used to test the performance with an orthogonal frequency multiplexing modulation (OFDM), which is one of the most used modulation schemes in wireless communication systems. info:eu-repo/grantAgreement/ES/DGA/GCM-T97 info:eu-repo/grantAgreement/ES/MINECO/TEC2014-58341-C4-2-R info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 1.592 2018 TELECOMMUNICATIONS 64 / 88 = 0.727 2018 Q3 T3 ENGINEERING, ELECTRICAL & ELECTRONIC 170 / 265 = 0.642 2018 Q3 T2 0.316 2018 Computer Networks and Communications 2018 Q2 Signal Processing 2018 Q2 Computer Science Applications 2018 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Garcia-Ducar, P.
