Book Synopsis Phase-Modulated Optical Communication Systems by : Keang-Po Ho
Download or read book Phase-Modulated Optical Communication Systems written by Keang-Po Ho and published by Springer Science & Business Media. This book was released on 2005-07-01 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fiber-optic communication systems have revolutionized our telecommunication infrastructures – currently, almost all telephone land-line, cellular, and internet communications must travel via some form of optical fibers. In these transmission systems, neither the phase nor frequency of the optical signal carries information – only the intensity of the signal is used. To transmit more information in a single optical carrier, the phase of the optical carrier must be explored. As a result, there is renewed interest in phase-modulated optical communications, mainly in direct-detection DPSK signals for long-haul optical communication systems. When optical amplifiers are used to maintain certain signal level among the fiber link, the system is limited by amplifier noises and fiber nonlinearities. Phase-Modulated Optical Communication Systems surveys this newly popular area, covering the following topics: - The transmitter and receiver for phase-modulated coherent lightwave systems - Method for performance analysis of phase-modulated optical signals - Direct-detection DPSK signal with fiber nonlinearities, degraded by nonlinear phase noise and intrachannel effects - Wavelength-division-multiplexed direct-detection DPSK signals - Multi-level phase-modulated optical signals, such as the four-phase DQPSK signal. Graduate students, professional engineers, and researchers will all benefit from this updated treatment of an important topic in the optical communications field.

Book Synopsis The Telephone Book by : Avital Ronell
Download or read book The Telephone Book written by Avital Ronell and published by U of Nebraska Press. This book was released on 1989-01-01 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: The telephone marks the place of an absence. Affiliated with discontinuity, alarm, and silence, it raises fundamental questions about the constitution of self and other, the stability of location, systems of transfer, and the destination of speech. Profoundly changing our concept of long-distance, it is constantly transmitting effects of real and evocative power. To the extent that it always relates us to the absent other, the telephone, and the massive switchboard attending it, plugs into a hermeneutics of mourning. The Telephone Book, itself organized by a "telephonic logic," fields calls from philosophy, history, literature, and psychoanalysis. It installs a switchboard that hooks up diverse types of knowledge while rerouting and jamming the codes of the disciplines in daring ways. Avital Ronell has done nothing less than consider the impact of the telephone on modern thought. Her highly original, multifaceted inquiry into the nature of communication in a technological age will excite everyone who listens in. The book begins by calling close attention to the importance of the telephone in Nazi organization and propaganda, with special regard to the philosophy of Martin Heidegger. In the Third Reich the telephone became a weapon, a means of state surveillance, "an open accomplice to lies." Heidegger, in Being and Time and elsewhere, elaborates on the significance of "the call." In a tour de force response, Ronell mobilizes the history and terminology of the telephone to explicate his difficult philosophy. Ronell also speaks of the appearance of the telephone in the literary works of Duras, Joyce, Kafka, Rilke, and Strindberg. She examines its role in psychoanalysis—Freud said that the unconscious is structured like a telephone, and Jung and R. D. Laing saw it as a powerful new body part. She traces its historical development from Bell's famous first call: "Watson, come here!" Thomas A. Watson, his assistant, who used to communicate with spirits, was eager to get the telephone to talk, and thus to link technology with phantoms and phantasms. In many ways a meditation on the technologically constituted state, The Telephone Book opens a new field, becoming the first political deconstruction of technology, state terrorism, and schizophrenia. And it offers a fresh reading of the American and European addiction to technology in which the telephone emerges as the crucial figure of this age.
