Since the publication of the first edition of Fundamentals of Digital Switching in 1983, there has been substantial improvement in digital switching technology and in digital networks. Packet switching has advanced from a low-speed data-oriented switching approach into a robust broadband technology which supports services ranging from low-speed data to video. This technology has eclipsed the flexibility of circuit switching. Fiber optic cable has advanced since the first edition and has substantially changed the technology of transmission. to research in optical devices to find a still better means of This success has led switching. Digital switching systems continue to benefit from the 100-fold improvement in the capabilities of semiconductor devices which has occurred during the past decade. The chip industry forecasts a similar escalation in complexity during the next 10 years. Networks of switching systems have changed due to regulatory policy reform in many nations, including the breakup of the Bell System in the United States, the introduction of new types of carriers in Japan, competition in the United Kingdom, and a reexamination of public policy in virtually all nations. Standards bodies have been productive in specifying new capabilities for future networks involving interactive and distributive services through STM and A TM technologies.

This book provides an introduction to the basic concepts in digital communications for readers with little or no previous exposure to either digital or analog communications. The intent is to help learners develop a firm understanding of digital communication system engineering--and to enable them to conduct system-level design and analysis for digital communication systems of the future. As a result, the book emphasizes the basic principles of digital communications theory and techniques, rather than presenting specific technologies for implementation. Chapter topics include probability and random variables--review and notation, introduction to random processes, linear filtering of random processes, frequency-domain analysis of random processes in linear systems, baseband transmission of binary data, coherent communications, noncoherent communications, intersymbol interference, and spread-spectrum communication systems. For individuals preparing for a career in wireless communications system design.

This book primarily focuses on the design of analog and digital communication systems; and has been structured to cater to the second year engineering undergraduate students of Computer Science, Information Technology, Electrical Engineering and Electronics and Communication departments. For better understanding, the basics of analog communication systems are outlined before the digital communication systems section. The content of this book is also suitable for the students with little knowledge in communication systems. The book is divided into five modules for efficient presentation, and it provides numerous examples and illustrations for the detailed understanding of the subject, in a thorough manner.

This book offers students, scientists, and engineers an extensive introduction to the theoretical fundamentals of digital communications, covering single-input single-output (SISO), multiple-input multiple-output (MIMO), and time-variant systems. Further, the main content is supplemented by a wealth of representative examples and computer simulations. The book is divided into three parts, the first of which addresses the principles of wire-line and wireless digital transmission over SISO links. Digital modulation, intersymbol interference, and various detection methods are discussed; models for realistic time-variant, wireless channels are introduced; and the equivalent time-variant baseband system model is derived. This book covers two new topics such as blockwise signal transmission and multicarrier modulation with orthogonal frequency-division multiplexing (OFDM) systems. Since not all readers may be familiar with this topic, Part II is devoted to the theory of linear time-variant systems. The generalized convolution is derived, and readers are introduced to impulse response, the delay spread function, and system functions in the frequency domain. In addition, randomly changing systems are discussed. Several new examples and graphs have been added to this book. In turn, Part III deals with MIMO systems. It describes MIMO channel models with and without spatial correlation, including the Kronecker model. Both linear and nonlinear MIMO receivers are investigated. The question of how many bits per channel use can be transmitted is answered, and maximizing channel capacity is addressed. Principles of space–time coding are outlined in order to improve transmission quality and increase data rates. In closing, the book describes multi-user MIMO schemes, which reduce interference when multiple users in the same area transmit their signals in the same time slots and frequency bands.

Public telephone networks are unrestricted dialing telephone networks that are available for public use to interconnect communications devices. This book describes the fundamentals of analog and digital telephone technology and communication and how the different types of analog and digital audio signals are described along with how their forms (PCM coding) differ in various parts of the world. You will learn about plain old telephone service (POTS) analog lines and integrated services digital network (ISDN) lines. The efficient GR-303 digital loop carrier (DLC) system is described along with how remote digital terminal (RDT) can allow a single communication line to provide telephone service for many businesses and homes. You will also learn how passive optical networks (PONs) are being used to deliver high capacity fiber optic communication to the premises (FTTP) communication lines direct to customers locations. The different types of switching systems are explained from circuit switched crossbar and time slot interchange (TSI) switches to packet voice and soft switches. You will learn how switches are interconnected with each other to form a global public telephone system. Multi-channel trunked lines are described including digital signaling (DS) lines, synchronous optical lines, and multi-channel optical (WDM) lines. You will learn how customers may lease lines or portions of communication lines for their own specific purposes. This book describes how telephone systems are controlled using signaling control messages, call processing, and SCP databases. You will learn about the different types of in-band tone signaling and of band common channel signaling system 7 (SS7). Also covered is how the public switched telephone network (PSTN) is beginning to use advanced intelligent network (AIN) to provide for advanced telephone service features. Explained are the key types of telephone voice, data, video and Centrex services. You will learn how customer care systems are transitioning from labor-intensive customer service representatives (CSRs) to services that are setup by customer self provisioning. Covered are the different types of digital subscriber line (DSL) including ADSL, ADSL2, HDSL, SDSL, and VDSL and how they connect the customer through digital subscriber line access modules (DSLAMs). You will learn that some DSL systems allow for the sharing of voice (analog) and digital (data) signals on the same line and how DSL data transmission capacity continues to increase to over 18 Mbps. You will discover why and how telephone system operators are converting their networks from circuit switched networks to packet voice systems. Find out how packet voice systems can offer the same or better quality of service (QoS) as traditional legacy systems.
