A History of ‘Religious History’

Journal of Religious History, EarlyView.
As a category denoting the analysis of religious actors across history disinterestedly and on their own terms, “religious history” is a relatively recent coinage. This article offers a brief contextualisation of the emergence of the field in the twentieth century. It distinguishes “religious history” from an older, “confessional” mode of ecclesiastical

‘Pro‐Germans in the Pulpits’: The Queensland Presbyterian Church and the Great War

Journal of Religious History, EarlyView.
During World War I, Protestant churches in Australia, on the whole, enthusiastically supported the war effort. The Queensland Presbyterian Church was a significant exception. This study analyses discord and tensions among its clergymen about what constituted an appropriate response to the war.

Survey on cognitive anti‐jamming communications [PDF]

IET Communications, 2020
In this study, the authors review various jamming and anti‐jamming strategies in the context of cognitive radios (CRs). The study explores different jamming models and classifies them according to their functionality. Furthermore, a study of jamming detection techniques is provided to enable a CR to identify different jamming signals.

Broadcast anti-jamming systems

IEEE International Conference on Networks. ICON '99 Proceedings (Cat. No.PR00243), 2005
In a traditional anti-jamming system a transmitter who wants to send a signal to a single sender spreads the signal power over a wide frequency spectrum with the aim of stopping a jammer from blocking the transmission. In this paper we consider the case that there are multiple receivers and the sender wants to broadcast a message to all receivers such ...

Hybrid Strategy of Anti-Jamming for MANET

International Journal of Organizational and Collective Intelligence, 2022
A mobile ad hoc network (MANET) is an autonomous system of mobile platforms called nodes which are free to move around randomly and without constraint. The Communication in this type of network is subject to many security issues such as jamming attacks, identifying the jamming attacks are challenging, which can increase the security threats, so ...

Anti-Jamming Filtering in the Autocorrelation Domain

IEEE Signal Processing Letters, 2004
An anti-jamming filtering technique is presented that it fully eliminates the jamming (or noncooperative) signal and its performance is noise-independent. This technique uses multiple receivers; a filtering process explores the nonoverlapping properties of the signals in the autocorrelation domain; and a matching of the input and the output statistics.

Anti-jamming of chaotic signals

Proceedings of Third International Conference on Signal Processing (ICSP'96), 2002
It is found that the amplitude-modulation disturbance can make the chaotic output signals of Chua's (1986) circuit jump into a limit cycle. This is because the limit cycles usually encircle the chaotic orbits in the phase portraits of the Chua's circuits. The four jamproof methods adopted in our physical experiments are the limiter for clipping the sum

Anti-jamming techniques for synthetic aperture radar

2009 IEEE International Geoscience and Remote Sensing Symposium, 2009
Excellent performance of SAR has aroused deep study of jamming techniques. This paper first discusses present jamming techniques and their shortcomings, then gives methodology of classifying ECCM of SAR, and at the same time, gives principle and results of signal design method, which combines orthogonal codes and random initial phase at each pulse, the
