Hybrid Analog-Digital Transceiver Designs for Cognitive Large-Scale Antenna Array Systems
Christos G. Tsinos, Sina Maleki, Symeon Chatzinotas +1
Milimeter wave (mmWave) band mobile communications can be a solution to the continuously increasing traffic demand in modern wireless systems. Even though mmWave bands are scarcely…
On the Performance Analysis of Underlay Cognitive Radio Systems: A Deployment Perspective
Ankit Kaushik, Shree Krishna Sharma, Symeon Chatzinotas +2
We study the performance of cognitive Underlay System (US) that employ power control mechanism at the Secondary Transmitter (ST) from a deployment perspective. Existing baseline mo…
Frequency of Arrival-based Interference Localization Using a Single Satellite
Ashkan Kalantari, Sina Maleki, Symeon Chatzinotas +1
Intentional and unintentional interferences are an increasing threat for the satellite communications industry. In this paper, we aim to localize an interference with unknown locat…
Directional Modulation via Symbol-Level Precoding: A Way to Enhance Security
Ashkan Kalantari, Mojtaba Soltanalian, Sina Maleki +2
Wireless communication provides a wide coverage at the cost of exposing information to unintended users. As an information-theoretic paradigm, secrecy rate derives bounds for secur…
Secure M-PSK Communication via Directional Modulation
Ashkan Kalantari, Mojtaba Soltanalian, Sina Maleki +2
In this work, a directional modulation-based technique is devised to enhance the security of a multi-antenna wireless communication system employing M-PSK modulation to convey info…
Symbol-Level Multiuser MISO Precoding for Multi-level Adaptive Modulation
Maha Alodeh, Symeon Chatzinotas, Bjorn Ottersten
Symbol-level precoding is a new paradigm for multiuser downlink systems which aims at creating constructive interference among the transmitted data streams. This can be enabled by…
