UAV communication interference analysis and anti-interference methods
Proceedings of the 2020 International Conference on Cyberspace Innovation of Advanced Technologies, 2020After 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.

Mitigating interference into communication satellites [PDF]
2001 IEEE Aerospace Conference Proceedings (Cat. No.01TH8542), 2002 This contribution outlines INTELSAT's efforts to reduce interference in the INTELSAT space segment by implementing an Interference Management Program (IMP) in conjunction with a Transmitter Locater System (TLS) tool to identify the geo-location of an interfering transmitter.

Noise interference with oral communication [PDF]
Acta Physica Hungarica, 1983 Communication by speech is the most direct connection between human beings. Noise disturbs this connection because it masks some components of acoustical features and therefore reduces the information content of speech. Diminishing of intelligibility does not only prevent communication but can bring forth dangerous situations.

Geolocation of communications satellite interference
2013 26th IEEE Canadian Conference on Electrical and Computer Engineering (CCECE), 2013Interference 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.

Enhancing interference mitigation in communication
Fourth International Conference on Information, Communications and Signal Processing, 2003 and the Fourth Pacific Rim Conference on Multimedia. Proceedings of the 2003 Joint, 2004spread spectrum is a technique that the transmitted signal is spreaded over a broader portion of the radio frequency band, by means of a code independent of the data. This technique will however allow a better performance over a fading channel, inherent privacy, and immunity to narrowband interference.

Interference multiple access communications
SPIE Proceedings, 2007The implementation of network centric warfare on the battlefield has driven the growing demand for high capacity warfighter communication systems. Although new high capacity SATCOM systems such as WGS are being introduced in the near term, these systems use the interference avoidance paradigm, which fundamentally limits overall network performance ...

Analysis of interference alignment for wireless communication with external interference
2014 International Telecommunications Symposium (ITS), 2014In order to better cope with the increasing levels of interference in wireless cellular systems, interference mitigation techniques that consider a certain degree of coordination/cooperation among cells have been recently employed, such as Joint Processing (JP) and Interference Alignment (IA).

On Covert Communication with Interference Uncertainty
2018 IEEE International Conference on Communications (ICC), 2018Covert 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.

Interference between communicating parallel processes
Communications of the ACM, 1972Various kinds of interference between communicating parallel processes have been examined by Dijkstra, Knuth, and others. Solutions have been given for the mutual exclusion problem and associated subproblems, in the form of parallel programs, and informal proofs of correctness have been given for these solutions.
