Abstract:

La cinquième génération de réseaux cellulaires (5G) a été une véritable révolution des technologies du réseau d'accès radio et du réseau mobile de base, se présentant comme la génération de rupture qui permet la cohabitation d'applications et usages extrêmement diversifiés, unifiés au sein d'une même technologie. Néanmoins, la 5G n'est qu'un début : de nouveaux scénarios et défis émergent. Par conséquent, la communauté des chercheurs prépare le terrain pour les systèmes cellulaires au-delà de la 5G (B5G). À cet égard, plusieurs technologies habilitantes sont étudiées. Outre la radio intelligen

Abstract:

Over the next decade, multi-antenna radios, including phased array and multiple-input-multiple-output (MIMO) radios, are expected to play an essential role in the next-generation of wireless networks. Phased arrays can reject spatial interferences and provide coherent beamforming gain, and MIMO technology promises to significantly enhance the system performance in the coverage, capacity, and user data rate through the beamforming or diversity/capacity gain which can substantially increase the range in wireless links, that are challenged from the transmitter (TX) power handling, receiver (RX) n

Abstract:

As fifth generation (5G) standards have been established and 5G commercial products are just around the corner, both academia and industry have started to look at requirements for beyond 5G networks. Network flexibility and long battery life are among the key requirements for beyond 5G wireless communication systems. These critical requirements, which have not been sufficiently addressed in the previous generations, are the focus of this thesis. The first half of this thesis explores two important use cases of drones to provide flexible communication networks. First, the performance of a ce

Abstract:

碩士<br>國立臺灣大學<br>電信工程學研究所<br>107<br>Enabling asynchronous multiuser uplink transmission is important and necessary for the next generation of wireless networks (5G) since it has to be able to meet the requirements for some scenarios, such as ultra-reliable low-latency communications (URLLC), and massive machine type communications (mMTC). In relaxed synchronization conditions, orthogonal frequency division multiplexing (OFDM) system, which is widely used in the fourth generation of the wireless network (4G), is easy to interfere adjacent users due to high out-of-subband emission (OSBE).

Abstract:

Il 5G sta compiendo una trasformazione significativa del panorama delle reti mobili, introducendo capacità flessibili ed eterogenee che coordinano armoniosamente numerose componenti tecniche dal momento che sono attualmente in fase di sviluppo una grande varietà di servizi avanzati, ognuno dei quali caratterizzato da requisiti diversi. Di conseguenza, appare naturale come il 5G non abbia un'unica interfaccia radio, bensì una famiglia di interfacce radio, tutte opportunamente inserite in un unico framework comune, al fine di rispondere adeguatamente ai diversi casi d'uso. Tuttavia, la gestione

Abstract:

The Orthogonal Frequency Division Multiplexing (OFDM) technology has been used in 4G and 5G mobile telecommunications systems. Despite its features and advanced results, it has some challenges to enhance spectral efficiency. Generalized Frequency Division Multiplexing (GFDM) is a new digital non-orthogonal multicarrier modulation concept. It aims to achieve higher spectral efficiency, better control of Out-Of-Band (OOB) emissions due to its flexibility to choose the pulse shaping filter, and obtain a reduction in Peak to Average Power Ratio (PAPR) compared to the OFDM. MIMO can further

Abstract:

The demand for wireless communication is ceaselessly increasing in terms of the number of subscribers and services. Future generations of cellular networks are expected to allow not only humans but also machines to be immersively connected. However, the radio frequency spectrum is already fully allocated. Therefore, developing techniques to increase spectrum efficiency has become necessary. This dissertation analyzes two spectrum sharing techniques that enable efficient utilization of the available radio resources in cellular networks. The first technique, called full-duplex (FD) communica
