Unitary Spreading for Robust LPI/AJ TRANSEC in CPM Systems
Tucker Hathaway, Daniel Chew
Adversarial feature extraction and blocking jamming threaten tactical CPM links. This paper presents a unitary spreading-based Transmission Security (TRANSEC) enhancement to obscur…
Improved OFDM Signal Cancellation through Window Estimation
Daniel Chew, Samuel Berhanu, Chris Baumgart +1
The ability to cancel an OFDM signal is important to many wireless communication systems including Power-Domain Non-orthogonal Multiple Access (PD-NOMA), Rate-Splitting Multiple Ac…
Persistent Weak Interferer Detection in WiFi Networks: A Deep Learning Based Approach
Andrew Adams, Richard F. Obrecht, Miller Wilt +3
In this paper, we explore the use of multiple deep learning techniques to detect weak interference in WiFi networks. Given the low interference signal levels involved, this scenari…
Covert Communications through Imperfect Cancellation
Daniel Chew, Christine Nguyen, Samuel Berhanu +2
We propose a method for covert communications using an IEEE 802.11 OFDM/QAM packet as a carrier. We show how to hide the covert message so that the transmitted signal does not viol…
