The proposed scheme is experimentally evaluated over a W-band millimeter wave radio-over fiber system. The evaluated NOMA-CAP system consists of six 1.25-GHz multiCAP bands and two NOMA levels with quadrature phase-shift keying and can provide an aggregated transmission rate of 30 Gbit/s. The proposed system can dynamically adapt to different user densities and data rate requirements. Bit error rate performance is evaluated in two scenarios: a low user density scenario where the system capacity is evenly split between two users and a high user density scenario where NOMA and multiCAP are combined to serve up to 12 users with an assigned data rate of 2.5 Gbit/s each. The proposed system demonstrates how NOMA-CAP allows flexible resource provisioning and can adapt data rates depending on user density and requirements. info:eu-repo/grantAgreement/ES/DGA/T25 info:eu-repo/grantAgreement/ES/MECD/FPU-13-00620 info:eu-repo/grantAgreement/ES/MICINN/TEC2014-59583-C2-1-R info:eu-repo/grantAgreement/ES/MINECO/TEC2013-46917-C2-2-R info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 3.652 2017 ENGINEERING, ELECTRICAL & ELECTRONIC 44 / 260 = 0.169 2017 Q1 T1 TELECOMMUNICATIONS 17 / 87 = 0.195 2017 Q1 T1 OPTICS 13 / 94 = 0.138 2017 Q1 T1 1.166 2017 Atomic and Molecular Physics, and Optics 2017 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Rommel, Simon Puerta, Rafael (orcid)0000-0002-4746-3139 Izquierdo, David Universidad de Zaragoza (orcid)0000-0003-3505-0078 Garcés, Juan Ignacio Universidad de Zaragoza Lázaro, José Antonio Vegas Olmos, Juan José Monroy, Ildefonso Tafur 5008 800 Universidad de Zaragoza Dpto.
