Найти книгу: "Bandwidth-Efficient Digital Modulation with Application to Deep-Space Communications"

An important look at bandwidth-efficient modulations with applications to today's Space program Based on research and results obtained at the California Institute of Technology's Jet Propulsion Laboratory, this timely book defines, describes, and then delineates the performance (power and bandwidth) of digital communication systems that incorporate a wide variety of bandwidth-efficient modulations appropriate for the design and implementation of space communications systems. The author compares the performance of these systems in the presence of a number of practical (non-ideal) transmitter and receiver characteristics such as modulator and phase imbalance, imperfect carrier synchronization, and transmitter nonlinearity. Although the material focuses on the deep space applications developed at the Jet Propulsion Laboratory, the presentation is sufficiently broad as to be applicable to a host of other applications dealing with RF communications. An important contribution to the scientific literature, Bandwidth-Efficient Digital Modulation with Application to Deep Space Communications * was commissioned by the JPL Deep Space Communications and Navigation System Center of Excellence * highlights many NASA-funded technical contributions pertaining to deep space communications systems * is a part of the prestigious Deep Space Communications and Navigation Series The Deep Space Communications and Navigation Series is authored by scientists and engineers with extensive experience in astronautics, communications, and related fields. It lays the foundation for innovation in the areas of deep space navigation and communications by disseminating state-of-the-art knowledge in key technologies.

While the success of Open Source software like Linux or Apache has been documented extensively throughout all mainstream media, the rise of PHP has gone largely unnoticed. Still, the Web scripting language PHP is the most popular module for the Apache Web server, according to an E-Soft survey (www.e-softinc.com/survey/). Netcraft studies have found that PHP is in use on over 6% of all Web domains in the world (see www.netcraft.com/survey).That’s an incredible market penetration for a rather specialized product.This popularity continues to rise exponentially. Increasingly, this is being reflected in traditional media: As of May, 2000, more than 20 books about PHP have been published in different languages, with more in the pipeline. Commercial players are beginning to join the bandwagon: PHP is included with Web servers, for example C2’s Stronghold, and Linux distributions. A new company, Zend Technologies, has been formed to provide commercial add-ons and support for PHP.A long list of large-scale Web sites employ PHP, as well as hundreds of thousands of small to medium Web sites.

The personal home page (PHP) server-side scripting language is particular well adapted to connecting HTML-based web pages to a backend database for dynamic content. This book explains the entire nuts-and-bolts process of the PHP application life cycle: requirements, design, development, maintenance and tuning. It shows how PHP can be used to design and develop highly manageable and secure applications to solve practical problems.

Written by members of the Oracle XML group, this is a must-have reference for all IT managers, DBAs, and developers who want to learn the best practices for using XML with Oracle’s XML-enabled products. Includes real-world case studies based on theauthors’ experience managing Oracle’s XML Discussion Forum - a community of 20,000+ XML component users.

Rizzoni is designed for the sophomore/junior level, Introduction to Electrical Engineering course required for non-EE majors. The most widely used book for this course, Rizzoni introduces non-majors to the three basic areas of electrical engineering: circuits, electronics, and electromechanics. The second edition continues the tradition of focusing on the topics and issues of interest to the non-electrical engineering student. To maintain student interest in these topics, Rizzoni provides numerous links between electrical engineering and other engineering fields.
