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, 2004
spread 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 between communicating parallel processes

Communications of the ACM, 1972
Various 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.

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.

Mitigating interference into communication satellites

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.

Communicative Interference and Failure

ITL - International Journal of Applied Linguistics, 1993
Lorsque des locuteurs de hongrois standard et des americains hongrois conversent, on observe differents types d'interference communicative qui peuvent avoir pour resultat un echec communicatif. Dans cet article l'auteur se propose de reanalyser la donnee de Kontra (1990) qui utilise la distinction entre echec pragmalinguistique et echec ...

Noise interference with oral communication

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.

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 Management in D2D Communication

2014
This chapter aims to provide a comprehensive study of the interference generated by enabling device-to-device (D2D) communication in cellular networks. We first categorize the D2D interference according to its causative factor, and investigate the characteristics and effects.

Inductive interference with communication circuits

Journal of the Institution of Electrical Engineers, 1924
The paper discusses interference between power circuits and telegraph and telephone circuits. A distinction is made between “radiation” and “induction.” The former cause produces both electric and magnetic effects and is used in radio-telegraphy. The conductivity of the earth, which is not a homogeneous body, should be taken into account.

Analysis of interference alignment for wireless communication with external interference

2014 International Telecommunications Symposium (ITS), 2014
In 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).
