Massive MIMO for Future Wireless Networks: Energy Efficiency, Interference Management and Symbiotic IoT Networks
DownloadSpring 2023
Due to the dramatic increase in wireless data traffic and the energy consumption of wireless networks, spectral- and energy-efficient wireless networks are imperative. Using multiple-input multiple-output (MIMO) transceiver structures and cell den- sification through small cell (SC) deployment...

Parallel Implementations of Detection Algorithms for MIMO Systems on The Graphics Processing Unit
DownloadSpring 2014
In this thesis, the acceleration of detection algorithms for multiple-input multipleoutput (MIMO) wireless systems is investigated. First we use the graphics processing unit (GPU), which provides thousands of parallel threads, to accelerate our detectors. The simulation environment for the...

Wireless relays offer benefits such as coverage extension and improving robustness. Selection of relays may provide further benefits. The best relays are selected based on the channel state information. However, due to feedback or scheduling delays, in practise, the relay and/or the source node can...
