Innovative Technologies for Fifth Generation Mobile Networks

Abstract

The telecommunications field is continuously and rapidly changing, especially while approaching its “Fifth Generation 5G” which is expected to introduce the concepts of Internet of Things (IoT), Sensor Networks and Machine to Machine (M2M) communication. In this thesis, the starting point will be investigating the effects of introducing such new concepts on the system requirements of today’s telecommunication systems and how they should be changed in order to cope up with the expected new framework and will end-up with introducing new methodologies that are more capable of working efficiently in such framework. At the beginning, a clear illustration of “Orthogonal Frequency Division Multiplexing” (OFDM) systems operation is provided where; the major drawbacks of these OFDM-based systems are highlighted concentrating on their high sensitivity to Timing-Offset (TO) and Carrier Frequency-Offset (CFO). OFDM systems apply highly exhaustive synchronization procedures in order to achieve the required level of synchronization. Majority of the work done in this thesis is concerned with the Universal Filtered Multi-Carrier (UFMC) technique that is introduced as an OFDM replaceme
