Abstract: Based on the bestseller "3G Evolution - HSPA and LTE for mobile broadband" and reflecting the ongoing success of LTE throughout the world, this book focuses on LTE with full updates including LTE-Advanced to provide a complete picture of the LTE system. Overview and detailed explanations are given for the latest LTE standards for radio interface architecture, the physical layer, access procedures, broadcast, relaying, spectrum and RF characteristics, and system performance. Key technologies presented include multi-carrier transmission, advanced single-carrier transmission, advanced receivers, OFDM, MIMO and adaptive antenna solutions, advanced radio resource management and protocols, and different radio network architectures. Their role and use in the context of mobile broadband access in general is explained. Both a high-level overview and more detailed step-by-step explanations of the LTE/LTE-Advanced implementation are given. An overview of other related systems such as GSM/EDGE, HSPA, CDMA2000, and WIMAX is also provided. This book is a 'must-have' resource for engineers and other professionals in the telecommunications industry, working with cellular or wireless broadband technologies, giving an understanding of how to utilize the new technology in order to stay ahead of the competition. The authors of the book all work at Ericsson Research and have been deeply involved in 3G and 4G development and standardisation since the early days of 3G research. They are leading experts in the field and are today still actively contributing to the standardisation of LTE within 3GPP.

TL;DR: A Kalman backpropagation neural network-based DDoS intrusion detection model that can be implemented in IoT dynamic environments, providing an intelligent intrusion detection mechanism against the second biggest threat to data traffic and transfer on IoT networks.
Abstract: The fifth-generation (5G) wireless communication systems associating with the high achievable data-transfer speeds will significantly affect the performance of IoT networks. On one hand, the internet goes through a dramatic transaction period that shapes every aspect of our lives, industry, and business where cloud computing, smart cities, and the Internet of Things (IoT) play a significant role in the advancement of data transfer, storing, and processing. On the other hand, it plays a significant role in emerging advanced versions of different types of cybersecurity attacks especially that are novel, hard-to-detect, and that of distributive never cease-fire characteristics. To mitigate these concerns, we present a distributed denial-of-service (DDoS) intrusion detection model that can be implemented in IoT dynamic environments, providing an intelligent intrusion detection mechanism against the second biggest threat to data traffic and transfer on IoT networks. Kalman backpropagation neural network-based DDoS intrusion detection is proposed in this work. The framework is validated through various simulations via the most up to date CICDDoS2019 dataset to demonstrate the effectiveness of the solution in terms of intrusion detection. the proposed solution achieved an average detection accuracy of 94% with 0.0952 false alarm rate and 97.49%, 91.22% for detection rate, and precision respectively.

TL;DR: An innovative mobile bot net infrastructure, composed by mobile agents, for the execution of denial of service attacks, proves that the chance of involving mobile bots is possible and shows that in virtue of reduced resource consumption the proposed system is particularly addicted to the mobile environment.
Abstract: The recent proliferation of smartphones and tablets leads to consider such devices as means for the execution of cyber-attacks. This scenario has rarely been considered earlier, since mobile devices always represented a target for cyber-criminals, rather than a vector to exploit. In this paper we introduce an innovative mobile bot net infrastructure, composed by mobile agents, for the execution of denial of service attacks. We prove that the chance of involving mobile bots is possible, comparing the proposed infrastructure to Low-Orbit Ion Cannon (LOIC), a well-known system in this context. Results show that in virtue of reduced resource consumption the proposed system is particularly addicted to the mobile environment. The idea of a mobile bot net is unexplored until now, therefore, the proposed system represents an important step in the mobile and cyber security field.

TL;DR: This paper discusses a novel technique, which is called the Equation-Method, which uses the Fast Fourier Transform to create a set of simultaneous equations which, when solved, return the amplitudes of the peaks before they were clipped.
Abstract: Orthogonal frequency division multiplexing (OFDM) is the digital modulation technique used by 4G and many other wireless communication systems. OFDM signals have significant amplitude fluctuations resulting in high peak to average power ratios which can make an OFDM transmitter susceptible to non-linear distortion produced by its high power amplifiers (HPA). A simple and popular solution to this problem is to clip the peaks before an OFDM signal is applied to the HPA but this causes in-band distortion and introduces bit-errors at the receiver. In this paper we discuss a novel technique, which we call the Equation-Method, for correcting these errors. The Equation-Method uses the Fast Fourier Transform to create a set of simultaneous equations which, when solved, return the amplitudes of the peaks before they were clipped. We show analytically and through simulations that this method can, correct all clipping errors over a wide range of clipping thresholds. We show that numerical instability can be avoided and new techniques are needed to enable the receiver to differentiate between correctly and incorrectly received frequency-domain constellation symbols.

TL;DR: A comprehensive survey on network architectures, communication protocols, transmission strategies, and optimization algorithms to improve the performance of multicast communications over mobile radio systems and supports research activities devoted to the identification of promising methodologies.
Abstract: Due to the increasing demand for pervasive video and broadcast-like applications, multicast and broadcast communications are expected to assume an important role in upcoming 5G systems. The current research trend is trying to reuse, extend, or adapt reference transmission strategies already designed for the conventional 4G technology. Nevertheless, apart the two reference and standardized methodologies, i.e., multimedia broadcast/multicast service and single cell-point to multipoint, many technical extensions and novel solutions were published in the literature so far. Therefore, in order to provide a clear overview on available solutions (already standardized or simply extending conventional approaches), the present work provides a comprehensive survey on network architectures, communication protocols, transmission strategies, and optimization algorithms to improve the performance of multicast communications over mobile radio systems. The core of the conducted study represents a structured taxonomy, able to properly classify scientific contributions based on their reference standard, targeted goal, addressed methodology, considered application domain, and obtained results. Taking into account this taxonomy, more than one hundred of scientific contributions are presented, classified, and reviewed. The study of the state-of-the-art is further enhanced with the discussion on important lessons learned, which clearly highlight the pros and cons of any investigated approach. A focus is also provided on the main issues on long term evolution multicasting that need to be better investigated, and determine the possible future research directions on this subject. The final goal of this paper is to support research activities devoted to the identification of promising methodologies, that efficiently support the delivery of real-time and on-demand video contents in a TV-like fashion.
