Channel Modeling and Physical Layer Optimization in Copper Line Networks

By: Rainer Strobel

This book investigates the physical layer aspects of high-speed transmission on twisted-pair copper wires, where the most performance-critical components are multi-input multi-output (MIMO) precoding and multi-line spectrum optimization as well as optimized scheduling of the transmission time slots on the fiber to the distribution point (FTTdp) copper link. The book brings theoretical results into the implementation, which requires the introduction of realistic channel models and more practical implementation constraints as found in the copper access network. A good understanding of the transmission medium, twisted-pair telephone cable bundles is the basis for this work. Starting from the analysis of measurement data from twisted-pair cable bundles at high frequencies, it presents a MIMO channel model for the FTTdp network, which allows the characteristic effects of high-frequency transmission on copper cable bundles in simulation to be reproduced and the physical layer transmission methods on the copper channels to be analyzed and optimize. The book also presents precoding optimization for more general power constraints and implementation constraints. The maximization of data rate in a transmission system such as G.fast or VDSL is a combinatorial problem, as the rate is a discrete function of the number of modulated bits. Applying convex optimization methods to the problem offers an efficient and effective solution approach that is proven to operate close to the capacity of the FTTdp channel. In addition to higher data rates, low power consumption is another important aspect of the FTTdp network, as it requires many access nodes that are supplied with power from the subscriber side over the twisted- pair copper wires. Discontinuous operation is a method of quickly adding and removing lines from the precoding group. To implement this, the system switches between different link configurations over time at a high frequency. The transmission times of all lines are jointly optimized with respect to the current rate requirements. Discontinuous operation is used to save power, but also makes it possible to further increase the data rates, taking the current subscriber traffic requirements into account. These methods are compared with theoretical upper bounds, using realistic channel models and conditions of a system implementation. The performance analysis provides deeper insights into implementation complexity trade-offs and the resulting gap to channel capacity.

Linux Universe

Installation and Configuration

By: Stefan Strobel,Rainer Maurer,Stefan Middendorf

Hailed in previous editions for its user-friendliness, this third edition of Linux Universe contains the newest Linux Kernel 2.0.25 on two fully configured CD-ROMs for easy installation. The new edition contains several powerful new features, including Java SDK (binary), Xemacs, Netatalk (Appletalk connectivity), and IP firewall administration tools. "The graphical configuration utility is simple to use and seems to work well. It works quickly and intelligently. When filling out the networking configuration, for example, it guesses most of the information once you type in the IP address." -LINUX JOURNAL

Linux - Unleashing the Workstation in Your PC

By: Stefan Strobel,Volker Elling

This book introduces the concepts and features of Linux. It describes the features and services of the Internet which have been instrumental in the rapid development and wide distribution of Linux and focuses on the graphical interface, network capability, and extended tools of Linux. It also gives an overview of the wide range of freeware applications available for Linux. Now completely revised and expanded to help the reader take full advantage of the high-performance of Linux 2.0, this third edition lists all of the currently supported hardware; provides the latest information on Linux as client/server; explains the newest applications including StarOffice 3.1, new graphics tools (including GIMP), Xemacs, and LyX; and presents the most up to date information on security and cryptography. Plus, there is a new UNIX command reference with entries grouped by purpose, as well as a new section on how to deal with errors. All in all, the most up-to-date information on Linux available!

Linux Universe

By: Stefan Strobel,Thomas Uhl,Rainer Maurer

Linux is a relatively new shareware Unix system for PCs (386 to Pentium) which was developed by an international community on the Internet. It is a viable alternative to commercial Unix workstations with characteristics comparable to a RISC workstation. This CD contains a complete Linux system and comes with a complete installation guide. The graphical administration tools make it easy to use even for novices.

Surprising Insights from the Unchurched and Proven Ways to Reach Them

By: Thom S. Rainer

We’ve read all the hot books on evangelism, we’ve attended scores of seminars—and still we’re not reaching the unchurched. Eighty to ninety percent of churchless Americans will never darken our culturally relevant, seeker-sensitive doors. What are we missing?Maybe we’ve been asking the wrong people. Instead of consulting the unchurched masses, it’s time we heard what the small but important minority who have recently begun attending a church have to say. What made the difference for them? What critical factors helped spark their faith in Jesus and drew them into the community of believers?Thom S. Rainer, dean of the Billy Graham School of Missions, Evangelism and Church Growth, shares the results and conclusions of his school’s groundbreaking survey of the formerly unchurched. At last, here are proven insights into what evangelistically effective churches are doing right. Flying in the face of much contemporary wisdom, the answers will surprise you.This is truly one of the most valuable resources you can own as a church leader. Filled with charts, graphs, and other visual aids, plus an abundance of true-life accounts, this book explodes common myths about the unchurched. You’ll discoverWhy pastors and doctrinal preaching are criticalThe enormous influence of family and relationships Which things matter more than we’d thought, and which matter lessWhat causes visitors to returnThe traits of unchurched-reaching leadersHow to preach effectively to the unchurchedHow to become a church for the unchurchedAnd much, much moreThis eye-opening compendium of information includes reproducible appendices that can help you fine-tune or even restructure your church. From one of the nations foremost authorities on evangelism and church growth, here are insights and tools that will change the way you think of and deal with--and win--unchurched men and women who long to connect with God.Photocopyable material includesUnchurched-Reaching Readiness InventoryChurch Health Survey
