Signal Processing for High Throughput Satellite Systems: Challenges in New Interference-Limited Scenarios
Ana I. Perez-Neira, Miguel Angel Vazquez, Sina Maleki +2
The field of satellite communications is enjoying a renewed interest in the global telecom market, and very high throughput satellites (V/HTS), with their multiple spot-beams, are…
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…
Secrecy Energy Efficiency Optimization for MISO and SISO Communication Networks
Ashkan Kalantari, Sina Maleki, Symeon Chatzinotas +1
Energy-efficiency, high data rates and secure communications are essential requirements of the future wireless networks. In this paper, optimizing the secrecy energy efficiency is…
Joint Power Control in Wiretap Interference Channels
Ashkan Kalantari, Sina Maleki, Gan Zheng +2
Interference in wireless networks degrades the signal quality at the terminals. However, it can potentially enhance the secrecy rate. This paper investigates the secrecy rate in a…
Censored Truncated Sequential Spectrum Sensing for Cognitive Radio Networks
Sina Maleki, Geert Leus
Reliable spectrum sensing is a key functionality of a cognitive radio network. Cooperative spectrum sensing improves the detection reliability of a cognitive radio system but also…
