Multi-Objective and Many-objective Optimization problems have been extensively solved through evolutionary algorithms over a few decades. Despite the fact that NSGA-II and NSGA-III are frequently employed as a reference for a comparative evaluation o

A combined non-orthogonal multiple access (NOMA) and multiband carrierless amplitude and phase modulation (multiCAP) scheme is proposed for flexible resource provisioning in coherent passive optical networks (PONs). While the proposed combination inc

Performance evaluation for 5G FWA in Quasi Static mmWave Channels: OFDM vs SC-QAM

Autor: Daniel Jaramillo-Ramirez, Rafael Puerta, Dario Estupinan

Publikováno v: LATINCOM

Fixed wireless access (FWA) is an alternative to fiber-to-the-home services thanks to new 5G cellular networks. It is one of the alternatives for the services offered in the new integrated access and backhaul (IAB) architecture. These point-to-point
