Download or read book Principles of Spread Spectrum Communication Systems written by Don Torrieri and published by Springer Nature. This book was released on 2022-04-12 with total page 715 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook, now in its 5th edition, provides updated state-of-the-art coverage of spread-spectrum communication systems with new applications throughout the book. In this edition, the author extends sections with more comprehensive details about many topics. Some of the more complex sections have been rewritten to make them easier to understand. New subsections, sections, figures, and problems have been added throughout the book. New or expanded topics include frequency-hopping systems with multisymbol CPFSK detection, derivations of spread-spectrum systems with differential data modulations, chaotic systems, channel-state information, and MIMO. As with previous edition, the author presents mathematical analyses of spread-spectrum systems that provide insights into their operations and limitations and are of theoretical and practical interest to both researchers and system designers. He includes updated problems at the end of each chapter, which are intended to assist readers in consolidating their knowledge and to give practice in analytical techniques. Eight appendices provide the mathematical tools that are useful in understanding the main text.

Download or read book Techniques for Eliminating Baseband Voice Interference with Telemetry for the Apollo Communication System written by G. Dickey Arndt and published by . This book was released on 1970 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excessive telemetry error rates caused by baseband voice interference occur in several modes of the Apollo communication system. Demodulation, using essentially nonlinear quadrature phase detection, causes voice terms to appear in the telemetry spectrum. In this report, two methods which effectively linearize the demodulation process are used to reduce the voice interference. One method uses a negative feedback loop incorporated around the present nonlinear phase detector. The other method uses a frequency-modulation demodulator preceded by a composite filter containing three band-pass filters in parallel. The theoretical development, construction, and testing of both methods are presented. Significant improvement in telemetry performance is obtained. Results show that voice interference to both the 1.6- and 51.2-kbps telemetry data is negligible for all spacecraft/ground-station conditions when using either of the two methods. It is recommended that the negative-feedback-loop method be implemented in the Manned Space Flight Network ground stations as a result of its relative simplicity and superior performance.

This book was released on 2012-12-06 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: The topic ·Stress and Strain· of this conference was ideally constrasted by the remoteness and quiet atmosphere of the meeting place Hotel Seehof In Ratzeburg, a small medieval town situated on a peninsula in lake "Kuchensee· east of Hamburg In northern Germany. With the participation of 53 leading experts from all over the world, the workshop covered the widest possible range from the advancement of bonding theory, new mechanistic insights into chemical transformations and physical properties of highly strained compounds to their use as building blocks In organic synthesis and even as probes Into the detection of enzyme mechanisms. Because of their specific reactivities small ring units can uniquely play their role in the construction of composite functionalities. Such functionalities can increase the elegance In natural and non-natural products syntheses, since they help to develop more convergent synthetic routes and Improve the necessary chemo-, regio-and stereo-selectivity. This book presents all of the 20 Invited lectures and is complemented with short versions of 12 contributed papers and 13 poster presentations. I am convinced that it will stimulate further rapid development of this field of organic chemistry, which recently has seen extensions into the bioorganic area as well as towards new materials. In fact, several ·supra-natural" -at first sight exotic -compounds are already available In useful quantities and are being exploited to create vastly new molecular devices, i. e. compounds with unprecedented molecular functions and polymers with unconventional properties.

Download or read book Biomedical and Resonance Optics written by Leonid V. Tanin and published by Springer Nature. This book was released on 2020-12-10 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses fundamentally new biomedical imaging methods, such as holography, holographic and resonant interferometry, and speckle optics. It focuses on the development of holographic interference microscopy and its use in the study of phase objects such as nerve and muscle fibers subjected to the influence of laser radiation, magnetic fields, and hyperbaric conditions. The book shows how the myelin sheath and even the axon itself exhibit waveguide properties, enabling a fresh new look at the mechanisms of information transmission in the human body. The book presents theoretically and experimentally tested holographic and speckle-optical methods and devices used for investigating complex, diffusely scattering surfaces such as skin and muscle tissue. Additionally, it gives broad discussion of the authors’ own original fundamental and applied research dedicated to helping physicians introduce new contact-less methods of diagnosis and treatment of diseases of the cardiovascular and neuromuscular systems into medical practice. The book is aimed at a broad spectrum of scientific specialists in the fields of speckle optics, holography, laser physics, morphology and cytochemistry, as well as medical professionals such as physiologists, neuropathologists, neurosurgeons, cardiologists and dentists.
