BLEXVFR: Designing a Mobile Assistant for Pilots [PDF]
Adjunct Publication of the 23rd International Conference on Mobile Human-Computer Interaction, 2021 Piloting an aircraft is a difficult task that requires high-level cognitive abilities. Few studies have investigated the use of cognitive assistants to support pilots. This study is a first step toward an in-flight assistant for light aircraft pilots.

Compressive Sensing-Based Secure Uplink Grant-Free Systems
Frontiers in Signal Processing, 2022 Compressive sensing (CS) has been extensively employed in uplink grant-free communications, where data generated from different active users are transmitted to a base station (BS) without following the strict access grant process. Nevertheless, the state-

Power Scalable Angle of Arrival Estimation Using Pilot Design With Orthogonal Subsequences
IEEE Open Journal of the Communications Society, 2021 Energy efficient array processing is critical to implement feasible solutions for directional communication in a mmWave channel. MmWave channels are highly susceptible to blockage and require frequent angle of arrival (AoA) estimation.

Joint Mutual Coherence and Total Coherence Pilot Design for OFDM Channel Estimation
IEEE Access, 2019 Existing works design the pilot based on the mutual coherence criterion or total coherence criterion alone. However, using the mutual coherence criterion or total coherence criterion alone to design the pilot will yield the sensing matrix which ...
