5G Software-Defined Heterogeneous Networks With Cooperation and Partial Connectivity

Software-Defined 5G Networks: Challenges, and Technologies

The commoditization of key processing components coupled with virtualization of infrastructure functions will lead to a radical change in the economics of mobile networks. The latter will help network providers (e.g., MNO, MVNO) move from proprietary hardware and software platforms towards open and flexible cellular systems based on general-purpose cloud infrastructures. In this context, 5G sys...

Real-Time Prototyping of 5G Software- Defined Networks: Part 3

Cross-Layer Software-Defined 5G Network

In the past few decades, the world has witnessed a rapid growth in mobile communication and reaped great benefits from it. Even though the fourth generation (4G) mobile communication system is just being deployed worldwide, proliferating mobile demands call for newer wireless communication technologies with even better performance. Consequently, the fifth generation (5G) system is already emerg...

Interference Minimization in 5G Heterogeneous Networks

In this paper, we focus on one of the representative 5G network scenarios, namely multi-tier heterogeneous cellular networks. User association is investigated in order to reduce the down-link co-channel interference. Firstly, in order to analyze the multi-tier heterogeneous cellular networks where the base stations in different tiers usually adopt different transmission powers, we propose a Tra...

Software Defined Radio and Heterogeneous Reconfigurable Hardware

Mobile wireless terminals tend to become multi-mode wireless communication devices. Furthermore, these devices become adaptive. Heterogeneous reconfigurable hardware provides the flexibility, performance and efficiency to enable the implementation of these devices. The implementation of an WCDMA and an OFDM receiver in the same coarse-grained reconfigurable MONTIUM processor is discussed. Keywo...
