Optimal Capacity And Energy Efficiency Of Massive Mimo Systems, Ahmed Alshammari
Optimal Capacity And Energy Efficiency Of Massive Mimo Systems, Ahmed Alshammari
Electronic Theses and Dissertations
A lot of effort has been made during the last two decades to study and apply the concepts of MIMO technology in most of the wireless standards. Therefore, a huge improvement in the performance of wireless communications has been made. However, Demand for wireless services has exponentially increased during the past ten years. Hence, high throughput is very important for all users to get the best experience with the offered services. This creates many technical challenges that are difficult to handle with the existing technology. Therefore, massive multiple input multiple output (massive MIMO) is a new technology that has been …

Meta-Routing: Synergistic Merging Of Message Routing And Link Maintenance, Mustafa A. Ayad
Electronic Theses and Dissertations
The maintenance of network connectivity is essential for effective and efficient mobile team operations. Achieving robust mobile ad hoc networks (MANETs) connectivity requires a capable link maintenance mechanism especially if the network experiences expected intermittent connectivity due to a hostile environment. One applicable example of such network scenarios is multi-robot exploration for urban search and rescue (USAR). With the proliferation of these robotic networks, communication problems such as the link maintenance problem are subject to be raised quickly. Although various routing protocols for wireless ad hoc networks have been proposed, they solve the problems of message routing and link maintenance …

The Bit Error Rate (Ber) Performance In Multi-Carrier (Ofdm) And Single-Carrier, Saleh M. Albdran
Electronic Theses and Dissertations
The spectacular growth of wireless communication tools has escalated the number of mobile subscribers from almost 700 million in 2000 to more than 4 billion in 2009. The huge number of subscribers has led to several issues with how service is provided. The high user demand has forced developers to overcome the problems of the old analog systems and to introduce OFDM as a promising technique that can fulfill users' high demands. This technique matches well with high data rate connection and provides a higher capacity for the subscribers' usage.
The OFDM, as a multi-carrier, is more complex than the …
