UAV communication interference analysis and anti-interference methods

Proceedings of the 2020 International Conference on Cyberspace Innovation of Advanced Technologies, 2020
After a century of development, UAVs have been mainly used as target drones at first, and later used for battlefield reconnaissance and surveillance. Now, UAVs have become integrated with multiple functions such as reconnaissance surveillance, ground attack, and communication relay and become a battlefield weapon.

Geolocation of communications satellite interference

2013 26th IEEE Canadian Conference on Electrical and Computer Engineering (CCECE), 2013
Interference from ground sources continues to be a serious problem for satellite communications operators. In this paper, algorithms for determining the geographic position of the source are discussed. One line of position can be derived from the time difference of arrival of signals received from two satellites spaced in longitude.

On Covert Communication with Interference Uncertainty

2018 IEEE International Conference on Communications (ICC), 2018
Covert communication can prevent the opponent from knowing that a wireless communication has occurred. If only the additive white Gaussian noise (AWGN) channels and ambient noise are taken into consideration, a square root law was obtained and the result shows that the privacy rate approaches zero asymptotically.

On the interference of communication on computation in Java

18th International Parallel and Distributed Processing Symposium, 2004. Proceedings., 2004
Summary form only given. Overlapping communication with computation is a well-known technique to increase application performance. While it is commonly assumed that communication and computation can be overlapped at no cost, in reality, they do contend for resources and thus interfere with each other.

Secret communication on interference channels

2008 IEEE International Symposium on Information Theory, 2008
We examine secret communication over interference channels, starting with a model in which communication is semi-secret in that secrecy may depend on other transmitters to follow an agreed-upon signaling strategy. We compare this to robustly-secret communication, in which each user must allow for other users to deviate unilaterally from an agreed-upon ...

Interference-Aware Interference Mitigation for Device-to-Device Communications

2014 IEEE 79th Vehicular Technology Conference (VTC Spring), 2014
This paper proposes a way of applying interference- aware interference mitigation algorithms to device- to-device (D2D) communications in cellular networks for system throughput improvement. One of main purposes for using D2D communications is to offload throughput passing through a base station in cellular networks.

Covert Communications in a Dynamic Interference Environment

2018 IEEE 19th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2018
Much of security research focuses on preventing an adversary from deciphering a message's content, but there are a number of applications that motivate the more challenging goal of “covert” communications: transmitter Alice conveying information to legitimate receiver Bob while preventing a capable and attentive adversary Willie from detecting the ...

Communicating with quantum interference

Optical Society of America Annual Meeting, 1991
In recent experiments1 the phenomenon of two-photon interference has been studied, and apparent nonlocal interference effects have been convincingly demonstrated.2 In all these experiments interference effects are not manifest in the singles count rates but appear in the coincidence rate or rate of detection of pair events and are a result of ...
