This book was released on 2018-03-13 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seminar paper from the year 2018 in the subject Computer Science - Commercial Information Technology, University of Applied Sciences Stuttgart, language: English, abstract: What is jamming? The theoretical principle behind it is the jamming of data transmission in general between a transmitter and a receiver. The practical principle defines however the exclusive jamming of the data receiver. At this point of transmission the signal is weakest and most open to attack. There are few ways to attack the data exchange between two wireless connected points. This paper gives an insight into communications jamming from the topic area of information security.
Book Synopsis Wireless Communications under Hostile Jamming: Security and Efficiency by : Tongtong Li
Download or read book Wireless Communications under Hostile Jamming: Security and Efficiency written by Tongtong Li and published by Springer. This book was released on 2018-10-10 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph is intended for the designers and would-be designers of secure and efficient wireless communication systems under intentional interference. Along with the widespread of wireless devices, especially reconfigurable software defined radios, jamming has become a serious threat to civilian communications. In this book, going beyond traditional communication system design that mainly focuses on accurate information transmission under benign environments, we aim to enhance the physical layer security of communication systems by integrating modern cryptographic techniques into transceiver design, so as to achieve secure high-speed transmission under hostile interference with high reliability and efficiency. We revisit existing jamming patterns, and introduce new jamming patterns. We analyze the weaknesses of existing anti-jamming techniques. We present innovative and feasible anti-jamming techniques, which can strengthen the inherent security of the 3G, 4G and the upcoming 5G systems with minimal and inexpensive changes to the existing CDMA, frequency hopping and OFDM schemes. We also provide benchmarks for system performance evaluation under various jamming scenarios through capacity analysis. This book includes design principles, in-depth theoretical analysis and practical design examples, and will be of interest to academic researchers as well as professionals in industry.

Book Synopsis Digital Communications Jamming by : Cem Sen
Download or read book Digital Communications Jamming written by Cem Sen and published by . This book was released on 2000-09-01 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this thesis is to model coherently detected BFSK, BPSK and QPSK, and noncoherently detected BFSK communications systems in the presence of additive white Gaussian Noise (AWGN) and different types of jamming signals by using MATLAB Communications Toolbox and Simulink. The theoretical results are available for the effect of AWGN on the performance of digital communication systems. To determine the performance of a system in the presence of AWGN and different types of jamming signals we need to use computer simulation. The results obtained by simulation are presented for bit-error rate (BER) as a function of signal-to-noise ratio (SNR) and signal-to-jamming ratio (SJR). As observed from the simulation results, different types of jamming affect each digital modulation technique differently.

Book Synopsis The Effects of Soviet Army Communications Jamming on the AIM Division Signal Battalion by : John R. Williamson
Download or read book The Effects of Soviet Army Communications Jamming on the AIM Division Signal Battalion written by John R. Williamson and published by . This book was released on 1980 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study attempts to show that the U.S. Army AIM division signal battalion can not provide reliable communications support when confronted with the current Soviet radioelectronic combat threat. The investigation is centered on the fact that the division maneuver commanders are not familiar with the difficulties and complexities of the communications-electronics mission in an electronic warfare environment and currently rely too heavily on electronic communications to maintain command and control on the battlefield. The AIM division signal battalion mission and its current radio systems are explained in detail. The doctrine, equipment, and known capabilities of the Soviet communications jamming organizations are examined. Recent computer based technical analyses of the effectiveness of the Soviet radioelectronic combat threat on division level communications is presented. The author concludes that current AIM division signal battalions would not be able to maintain reliable commnand and control communications systems on the modern electronic battlefield when confronted with the full effects of the Soviet radioelectronic combat threat.

Book Synopsis Blind Massive MIMO Base Stations by : Marcus Karlsson
Download or read book Blind Massive MIMO Base Stations written by Marcus Karlsson and published by Linköping University Electronic Press. This book was released on 2018-08-15 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: Massive MIMO (Multiple-Input--Multiple-Output) is a cellular-network technology in which the base station is equipped with a large number of antennas and aims to serve several different users simultaneously, on the same frequency resource through spatial multiplexing. This is made possible by employing efficient beamforming, based on channel estimates acquired from uplink reference signals, where the base station can transmit the signals in such a way that they add up constructively at the users and destructively elsewhere. The multiplexing together with the array gain from the beamforming can increase the spectral efficiency over contemporary systems. One challenge of practical importance is how to transmit data in the downlink when no channel state information is available. When a user initially joins the network, prior to transmitting uplink reference signals that enable beamforming, it needs system information---instructions on how to properly function within the network. It is transmission of system information that is the main focus of this thesis. In particular, the thesis analyzes how the reliability of the transmission of system information depends on the available amount of diversity. It is shown how downlink reference signals, space-time block codes, and power allocation can be used to improve the reliability of this transmission. In order to estimate the uplink and downlink channels from uplink reference signals, which is imperative to ensure scalability in the number of base station antennas, massive MIMO relies on channel reciprocity. This thesis shows that the principles of channel reciprocity can also be exploited by a jammer, a malicious transmitter, aiming to disrupt legitimate communication between two single-antenna devices. A heuristic scheme is proposed in which the jammer estimates the channel to a target device blindly, without any knowledge of the transmitted legitimate signals, and subsequently beamforms noise towards the target. Under the same power constraint, the proposed jammer can disrupt the legitimate link more effectively than a conventional omnidirectional jammer in many cases. Massiv MIMO (eng: Multiple-Input--Multiple-Output) är en teknologi inom cellulär kommunikation som förutspås ha en betydande roll i framtida kommunikationssystem på grund av de många fördelar som denna teknologi medför. Massiv MIMO innebär att basstationen har ett stort antal antenner där varje antenn kan styras individuellt. De många antennerna gör att basstationen kan rikta de elektromagnetiska signalerna på ett sådant sätt att de förstärks på positioner där användarna befinner sig men släcks ut i övrigt. Detta i sin tur innebär att flera användare kan betjänas samtidigt, på samma frekvensband utan att de stör varandra. Detta medför att massiv MIMO kan erbjuda en högre datatakt än nutida cellulära kommunikationssystem. För att kunna rikta signalerna på ett effektivt sätt måste basstationen känna till kanalen, eller utbredningsmiljön, mellan sig själv och de användare som betjänas. När en användare precis kommer in i systemet vet basstationen inte var användaren befinner sig, men måste likväl tillgodose användaren med information om hur systemet fungerar. Nu måste alltså basstationen kommunicera med användaren, utan möjligheten att kunna rikta signalen på ett effektivt sätt. Det är detta problem som vi i huvudsak studerar i denna avhandling: hur man kan utnyttja de många antennerna på basstationen för att skicka information till användarna utan någon kanalkännedom. Vi studerar även hur en gruppantenn med många antenner, baserad på samma teknologi som massiv MIMO, kan användas som en störsändare. Störsändarens mål är att hindra kommunikationen mellan två enheter på ett effektivt sätt. En störsändare med ett stort antal antenner kan, utan någon kännedom av vad de två enheterna skickar, i många fall prestera bättre än en konventionell störsändare på grund av att störsignalen kan riktas mot en specifik enhet.
