Interference and noise cancellation for joint communication radar (JCR) system based on contextual information
Christantus O. Nnamani, Mathini Sellathurai
This paper examines the separation of wireless communication and radar signals, thereby guaranteeing cohabitation and acting as a panacea to spectrum sensing. First, considering th…
Gridded UAV Swarm for Secrecy Rate Maximization with Unknown Eavesdropper
Christantus O. Nnamani, Muhammad R. A. Khandaker, Mathini Sellathurai
This paper considers grid formation of an unmanned aerial vehicle (UAV) swarm for maximizing the secrecy rate in the presence of an unknown eavesdropper. In particular, the UAV swa…
Joint Beamforming and Location Optimization for Secure Data Collection in Wireless Sensor Networks with UAV-Carried Intelligent Reflecting Surface
Christantus O. Nnamani, Muhammad R. A. Khandaker, Mathini Sellathurai
This paper considers unmanned aerial vehicle (UAV)-carried intelligent reflecting surface (IRS) for secure data collection in wireless sensor networks. An eavesdropper (Eve) lurks…
UAV-Aided Jamming for Secure Ground Communication with Unknown Eavesdropper Location
Christantus O. Nnamani, Muhammad R. A. Khandaker, Mathini Sellathurai
This paper investigates unmanned aerial vehicle (UAV)-aided jamming technique for enabling physical layer keyless security in scenarios where the exact eavesdropper location is unk…
