Multiuser Multi Input Single Output (MU-MISO) Beamforming for 5G Wireless and Mobile Networks. A Road Map for Fast and Low Complexity User Selection, Beamforming Scheme Through a MU-MISO for 5G Wireless and Mobile Networks
Multi-User Multi-Input Multi-Output (MU-MIMO) systems are considered to be the sustainable technologies of the current and future of the upcoming wireless and mobile networks generations. The perspectives of these technologies under several scenarios is the focus of the present thesis. The initial …

Resource allocation and physical layer security in wireless communication systems
… of resource allocation is investigated in multiuser, multi-antenna downlink wireless systems in which spatial multiplexing is employed in the physical layer. The thesis consists of two main parts; in the first, the interest is focused on optimizing system's performance in terms of users' …

Channel state quantization in MIMO broadcast systems : architectures and codes
… This thesis studies the problem of multi-user multiple-antenna broadcast system design with an emphasis on the role that channel feedback plays in a network setting. We develop new design principles for channel feedback design in such systems and show that the system designer is afforded …

Deconstructing the room-temperature emission spectra of nanocrystals using Photon-Correlation Fourier Spectroscopy
… spectra with large sample statistics, without user selection bias, with high signal-to-noise ratios, and at fast timescales. With S-PCFS, we directly and quantitatively deconstruct the ensemble spectra of nanocrystals into contributions from the average single-NC homogeneous linewidth, spectral …

Resource allocation in coordinated multipoint long term evolution-advanced networks
… consider various diversities offered in multiuser wireless networks, particularly in frequency, spatial and time dimensions. The primary objective of this research is to develop resource allocation strategy for CoMP network that can provide high QoS. The resource allocation algorithm is …

Spectrum sharing in next generation wireless communication networks
… a hierarchical access model with three tiers of users: incumbents, Priority Access Licensees (PAL) and General Authorised Access (GAA) users. We propose a PAL-GAA co-channel interference mitigation technique that does not expose base station locations. The distribution of the aggregate …

Low-Latency Massive MIMO Design over Practical Channels
… Surprisingly, I find that geolocational far-away user channels can still be of high correlation even for the base-station with 64 antennas. More specifically, the mutual channel correlation between close-by users does not reduce with array size beyond 20. Using spatial signal processing and …

Privacy Preservation for Cloud-Based Data Sharing and Data Analytics
… analytics services. Cloud computing has enabled users to store, process, and communicate their personal information through third-party services. It has also raised privacy issues regarding losing control over data, mass harvesting of information, and un-consented disclosure of personal content. …
