[null,null,null,"Sommario/riassunto","Presents the technological advancements that enable high spectral-efficiency and high-capacity fiber-optic communication systems and networks This book examines key technology advances in high spectral-efficiency fiber-optic communication systems and networks, enabled by the use of coherent detection and digital signal processing (DSP). The first of this book's 16 chapters is a detailed introduction. Chapter 2 reviews the modulation formats, while Chapter 3 focuses on detection and error correction technologies for coherent optical communication systems. Chapters 4 and 5 are devoted to Nyquist-WDM and orthogonal frequency-division multiplexing (OFDM). In chapter 6, polarization and nonlinear impairments in coherent optical communication systems are discussed. The fiber nonlinear effects in a non-dispersion-managed system are covered in chapter 7. Chapter 8 describes linear impairment equalization and Chapter 9 discusses various nonlinear mitigation techniques. Signal synchronization is covered in Chapters 10 and 11. Chapter 12 describes the main constraints put on the DSP algorithms by the hardware structure. Chapter 13 addresses the fundamental concepts and recent progress of photonic integration. Optical performance monitoring and elastic optical network technology are the subjects of Chapters 14 and 15. Finally, Chapter 16 discusses spatial-division multiplexing and MIMO processing technology, a potential solution to solve the capacity limit of single-mode fibers. ́Ø Contains basic theories and up-to-date technology advancements in each chapter ́Ø Describes how capacity-approaching coding schemes based on low-density parity check (LDPC) and spatially coupled LDPC codes can be constructed by combining iterative demodulation and decoding ́Ø Demonstrates that fiber nonlinearities can be accurately described by some analytical models, such as GN-EGN model ́Ø Presents impairment equalization and mitigation techniques Enabling Technologies for High Spectral-efficiency Coherent Optical Communication Networks is a reference for researchers, engineers, and graduate students.

[null,null,null,"Sommario/riassunto","With insight and originality, Michael Fellman argues that terrorism, in various forms, has been a constant and driving force in American history. In part, this is due to the nature of American republicanism and Protestant Christianity, which he believes contain a core of moral absolutism and self-righteousness that perpetrators of terrorism use to justify their actions. Fellman also argues that there is an intrinsic relationship between terrorist acts by non-state groups and responses on the part of the state; unlike many observers, he believes that both the action and the reaction constitute terrorism.Fellman's compelling narrative focuses on five key episodes: John Brown's raid on Harpers Ferry; terrorism during the American Civil War, especially race warfare and guerrilla warfare; the organized \"White Line\" paramilitary destruction of Reconstruction in Mississippi; the Haymarket Affair and its aftermath; and the Philippine-American war of 1899-1902. In an epilogue, he applies this history to illuminate the Bush-Cheney administration's use of terrorism in the so-called war on terror. In the Name of God and Country demonstrates the centrality of terrorism in shaping America even to this day."]
