We consider a wireless source localization network in which target node emits signals that are used by anchor nodes to estimate the position. In addition and nodes, there can also exist eavesdropper jammer aim position of degrade accuracy localization, respectively. first propose problem selection with goal optimally placing given number subset possible positions as accurately possible. As perf...

Abstract New GNSS applications demand resilience against radio interference and high position accuracy. Separately, these demands can be fulfilled by multi-antenna systems using spatial filtering carrier-phase positioning algorithms like real-time kinematic (RTK), respectively. However, combining approaches encounters a severe issue: The induces phase offset into the measured carrier l...

Louis Dressel is a Ph.D. candidate in the Aeronautics and Astronautics Department at Stanford University. There, he works on a joint project with both the Stanford Intelligent Systems Lab and the GPS Research Laboratory implementing control algorithms for a jammer-hunting UAV. He received his B.S. in Aerospace Engineering with a minor in Computer Science from Georgia Tech in 2013 and his Master...

Reconfigurable intelligent surfaces (RISs) can potentially combat jamming. It is non-trivial to perform holistic selections of users, data streams, and modulation-coding modes for all subchannels, RIS configuration in a downlink multiuser OFDMA system under jamming attacks, because mixed-integer program nature difficulties acquiring the channel state information (CSI) channels from an uncoopera...

the production, distribution, and consumption of information are the most important development indices of any nation. plenty of opportunities were created by e-learning which have overall paved the grounds for and enriched the presentation of learning materials through advanced audiovisual educational facilities. such learning environments are by and large flexible and provide more appropriate...
