We consider a full duplex (FD) multiple-input multiple-output (MIMO) underlay cognitive
radio cellular network, in which an FD secondary base-station (BS) serves multiple half …

In this paper, we investigate the robust power allocation issue in orthogonal frequency
division multiplexing-based cognitive radio networks (CRNs) with unavoidable uncertainties …

We consider optimal linear precoder and decoder designs in a multi-cell multiple-input
multiple-output system, where base stations and mobile users are both operating in full …

With increasing emphasis on incorporating energy awareness in future communication
systems, it is desirable to explore power-efficient resource allocation techniques. Therefore …

For the realistic case where there is no secondary snapshot that does not contain the
desired signal and exhibits the statistical characteristics similar to the snapshot under test …

In this thesis, we analyze the performance of three promising technologies being considered
for future fifth generation (5G) and beyond wireless communication systems, with primary …

In this paper, we investigate the angle-domain spectrum opportunities of secondary users
with directional transmission, and analyze the detection probability of spectrum holes. We …

Transmission over interference channel often relies on the use of robust precoder due to a
lack of accurate channel state information, with performance often depending on the …

Cognitive radio (CR) is one of promising techniques to alleviate the spectrum scarcity
resulting from the increasing demand for wireless services and the exclusive spectrum …

Abstract Device-to-device (D2D) communications technology is currently being investigated
as a potential enabler for the fifth generation (5G) communication networks. Significant …
