Análisis para determinar el rendimiento de las formas de onda ortogonal y no ortogonal en redes inalámbricas 5G y posteriores

Abstract

With the development of technology, new information transmission demands have posed an unprecedented challenge for the next generation cellular system. In addition to traditional voice and data services via mobile phones, the 5G network is also expected to support traffic that is fundamentally different from the traditional one, such as the transmission of small packets via massive machine-type communications (MTC) or Internet of things (IoT). That is why filter-based waveforms have been studied recently, in order to provide the requirements for waveform design in 5G networks. The key factor why filter-based waveforms can outperform OFDM in 5G networks is that they can support asynchronous transmission by reducing OOBs through different filter designs. Therefore, in the present investigation, it is intended to generate an analysis for the study of orthogonal and non-orthogonal waveforms in future 5G and later wireless networks, verifying their underlying characteristics, as well as a complete comparison in terms of different metrics of performance, which provides a general understanding of these waveforms.
