This book gives a detailed overview of a universal Maximum Likelihood (ML) decoding technique, known as Guessing Random Additive Noise Decoding (GRAND), has been introduced for short-length and high-rate linear block codes. The interest in short channel codes and the corresponding ML decoding algorithms has recently been reignited in both industry and academia due to emergence of applications with strict reliability and ultra-low latency requirements . A few of these applications include Machine-to-Machine (M2M) communication, augmented and virtual Reality, Intelligent Transportation Systems (ITS), the Internet of Things (IoTs), and Ultra-Reliable and Low Latency Communications (URLLC), which is an important use case for the 5G-NR standard.GRAND features both soft-input and hard-input variants. Moreover, there are traditional GRAND variants that can be used with any communication channel, and specialized GRAND variants that are developed for a specific communication channel. This book presents a detailed overview of these GRAND variants and their hardware architectures.The book is structured into four parts. Part 1 introduces linear block codes and the GRAND algorithm. Part 2 discusses the hardware architecture for traditional GRAND variants that can be applied to any underlying communication channel. Part 3 describes the hardware architectures for specialized GRAND variants developed for specific communication channels. Lastly, Part 4 provides an overview of recently proposed GRAND variants and their unique applications.This book is ideal for researchers or engineers looking to implement high-throughput and energy-efficient hardware for GRAND, as well as seasoned academics and graduate students interested in the topic of VLSI hardware architectures. Additionally, it can serve as reading material in graduate courses covering modern error correcting codes and Maximum Likelihood decoding for short codes.

Das Gebiet der heutigen Ukraine gehörte zu den zentralen Tatorten der deutschen Besatzungsverbrechen und des Holocaust. Im September 1941 richteten die Deutschen dort das Reichskommissariat Ukraine ein, das zum Zeitpunkt seiner größten Ausdehnung aus Teilen des damaligen Ostpolens sowie der Sowjetrepubliken Belarus und Ukraine bestand. Zur Jahreswende 1941/42 ließ das Reichssicherheitshauptamt dort auch stationäre Dienststellen der Kommandeure der Sicherheitspolizei und des SD aufbauen. Sie führten weitgehend die verbrecherische Tätigkeit der sogenannten Einsatzgruppen fort, die weiter nach Osten vorstießen. Doch mit einem Unterschied: Sie waren gekommen, um zu bleiben und die Dystopie eines deutsch-dominierten Osteuropas in die Praxis umzusetzen. In der Folge erschossen die Angehörigen dieser Dienststellen unzählige als Juden und Roma verfolgte Menschen und Kriegsgefangene, errichteten ein eigenes Lagersystem, verfolgten den Widerstand, richteten eine einheimische Kriminalpolizei ein und nahmen aktiv Einfluss auf die Kirchenpolitik. Die Studie untersucht erstmals die Geschichte und das Personal der Dienststellen im Reichskommissariat Ukraine und wirft damit auch neues Licht auf die Praxis der Besatzung und den Holocaust.

This book uses digital radios as a challenging design example, generalized to bridge a typical gap between designers who work on algorithms and those who work to implement those algorithms on silicon. The author shows how such a complex system can be moved from high-level characterization to a form that is ready for hardware implementation. Along the way, readers learn a lot about how algorithm designers can benefit from knowing the hardware they target and how hardware designers can benefit from a familiarity with the algorithm. The book shows how a high-level description of an algorithm can be migrated to a fixed-point block diagram with a well-defined cycle accurate architecture and a fully documented controller. This can significantly reduce the length of the hardware design cycle and can improve its outcomes. Ultimately, the book presents an explicit design flow that bridges the gap between algorithm design and hardware design.Provides a guide to baseband radio design for Wi-Fi and cellular systems, from an implementation-focused, perspective;Explains how arithmetic is moved to hardware and what the cost of each operation is in terms of delay, area and power;Enables strategic architectural decisions based on the algorithm, available processing units and design requirements.

"Kyiv, 1919. World War I has ended in Western Europe, but to the East, six factions continue to vie for control of Ukraine. Amidst the political turmoil, young Samson Kolechko is forced to place his engineering career on hold. But in the city of Kyiv everything remains up for grabs and new opportunity lurks just around the corner. When two Red Army soldiers commandeer his home, Samson's life is completely upended. But as Samson juggles his personal life -including a budding romance with the ingenious Nadezhda, a statistician helping run the city's census- with the soldiers' intrusion, he winds up overhearing their secret plans. Deciding to report them, Samson instead finds himself unwittingly recruited as an investigator for the city's new police force. His first case involves two murders, a long bone made of pure silver, and a suit of decidedly unusual proportions tailored from fine English cloth. The odds stacked against him, Samson turns to Nadezhda, who proves to be more than his match."--Provided by publisher.

Western academics, experts, and journalists specializing in Eastern Europe, Russia and Eurasia have grappled with two fundamental analytical crises in connection with the 1991 disintegration of the USSR and Russiäs 2014 invasion of Ukraine. Both crises were brought about by a similar lack of understanding of Moscow¿s inability to view its neighbors, in particular Ukraine, as not possessing sovereignty and not treating them as independent states. Typically, they downplayed the historic and current role of Russian imperialism and nationalism.The book¿s contributors investigate how the Kremlin¿s recent turbo-charging of Russiäs information warfare, 24-hour TV, and social media activity has expanded on traditional pro-Russian sentiments among Western academics, experts, and journalists. The authors analyze the downplaying of Russian nationalism, misinterpretations of the 2014 crisis, sympathetic portrayals of Crimeäs occupation, and the use of the term ¿civil war¿ rather than ¿Russian-Ukrainian war¿ for the Donbas conflict in academia as well as the think tank world and media in the UK, Germany, Poland, Czech Republic, Japan, USA, and Canada.

This book demonstrates that the reliable and secure communication performance of maritime communications can be significantly improved by using intelligent reflecting surface (IRS) aided communication, privacy-aware Internet of Things (IoT) communications, intelligent resource management and location privacy protection. In the IRS aided maritime communication system, the reflecting elements of IRS can be intelligently controlled to change the phase of signal, and finally enhance the received signal strength of maritime ships (or sensors) or jam maritime eavesdroppers illustrated in this book.The power and spectrum resource in maritime communications can be jointly optimized to guarantee the quality of service (i.e., security and reliability requirements), and reinforcement leaning is adopted to smartly choose the resource allocation strategy. Moreover, learning based privacy-aware offloading and location privacy protection are proposed to intelligently guarantee the privacy-preserving requirements of maritime ships or (sensors). Therefore, these communication schemes based on reinforcement learning algorithms can help maritime communication systems to improve the information security, especially in dynamic and complex maritime environments.This timely book also provides broad coverage of the maritime wireless communication issues, such as reliability, security, resource management, and privacy protection. Reinforcement learning based methods are applied to solve these issues. This book includes four rigorously refereed chapters from prominent international researchers working in this subject area. The material serves as a useful reference for researchers, graduate students. Practitioners seeking solutions to maritime wireless communication and security related issues will benefit from this book as well.

The war in Ukraine did not start on 24 February 2022. It began eight years earlier in eastern Ukraine¿s Donbas region. In his new book, Jakob Hauter investigates the escalation of violence in the spring and summer of 2014. He demonstrates that, contrary to popular belief, the pre-2022 conflict was not a civil war. Ukraine has been fighting a Russian invasion since the armed conflict¿s very beginning. Hauter arrives at this conclusion based on a thorough review of the digital open source information (DOSI) available on the Internet. He argues that social science research needs theoretical and methodological innovation to operate in the abundant but murky information environment surrounding the Donbas War and other conflicts of the social media age. To address this challenge, he develops an escalation sequence model which divides the formative phase of the Donbas War into six critical junctures. He then combines the social science methodology of process tracing with DOSI analysis to investigate the causes of these critical junctures. For each juncture, Hauter assesses the available evidence of domestic causes and Russian interference, reaching the conclusion that, in most cases, there is convincing evidence that Russian involvement was the primary cause of armed escalation.¿This excellent, meticulously researched book is important. Not only does it provide fresh insights based on forensic analysis into the escalation of violence in Ukraine¿s Donbas region in 2014, it breaks new methodological ground: It shows how process tracing and the use of digital open source information can be combined in a rigorous way to deal with the informational challenges associated with conflict. Russiäs Overlooked Invasion brings much-needed transparency to an opaque but vital subject.¿¿Ben Noble, Associate Professor of Russian Politics, UCL SSEES¿Most previous accounts of the war in Eastern Ukraine have not gone beyond generalities. Hauter uses open source Intelligence for a forensic analysis, breaking down the events leading to war into six critical junctures, in four of which Russia is shown to have been the primary actor. Without Russia, moreover, there would have been no necessary progression through the six phases, and a containable conflict would not have become a hot war.¿¿Andrew Wilson, Professor of Ukrainian Studies, UCL SSEES
