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…
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…
