Prototipos de redes LTE en base a tecnología de radio definida por software e integración de la tecnología de radio sobre fibra en redes móviles: Análisis de la integración de tecnologías de radio sobre fibra en redes móviles: Caso de estudio técnica GFDM.

Abstract

The radio system over fiber in recent years has been an essential part of integrated high-performance networks, since it allows combining wireless communication systems with optical systems. The implementation of waveforms in 5G infrastructures is carried out in order to improve the use of the frequency spectrum of that infrastructure. Therefore, for the current project it is decided to use the non-orthogonal waveform of the Generalized Frequency Division Multiplexing transmission technique to analyze its performance within a RoF system. Analysis that holds in the context of a 5G network. The combination of these systems is done through a co-simulation of Matlab with Optsim, in which a link is designed that simulates a fronthaul environment of a Next Generation Radio Access Network. A link that uses a passive optical network (PON) to transmit a radio frequency signal. By using different modulation schemes within the simulation of that link, different configurations are obtained that provide different transmission speeds. Information that is compared for the purpose of determining performance values such as Bit Error Rate (BER) and Error Vector Magnitude (EVM) according to configuration parameters.
