Addressing the fundamental technologies and theories associated with designing complex communications systems and networks, Principles of Communications Networks and Systems provides models and analytical methods for evaluating their performance. Including both the physical layer (digital transmission and modulation) and networking topics, the quality of service concepts belonging to the different layers of the protocol stack are interrelated to form a comprehensive picture. The book is designed to present the material in an accessible but rigorous manner. It jointly addresses networking and transmission aspects following a unified approach and using a bottom up style of presentation, starting from requirements on transmission links all the way up to the corresponding quality of service at network and application layers. The focus is on presenting the material in an integrated and systematic fashion so that students will have a clear view of all the principal aspects and of how they interconnect with each other. A comprehensive introduction to communications systems and networks, addressing both network and transmission topics Structured for effective learning, with basic principles and technologies being introduced before more advanced ones are explained Features examples of existing systems and recent standards as well as advanced digital modulation techniques such as CDMA and OFDM Contains tools to help the reader in the design and performance analysis of modern communications systems Provides problems at the end of each chapter, with answers on an accompanying website

Due to the competitions between the telecommunication service providers, the required capacities are increasing all the time. It is important for these providers to develop a network that can transfer more data bytes from one place to another. In addition, the mobile traffic and the internet services need more capacities in the telecommunication networks. Therefore, it is mandatory for the networks to handle large amounts of data in a fast and a reliable way. Of course, one possibility would be Ethernet traffic, but in cellular transmission networks there are a strict requirement for delay, data loss and synchronization and this is why the Ethernet is not yet supported.The Synchronous Digital Hierarchy (SDH) is one answer for increasing the network data traffic. For example, if we need to transfer 63 × 2.048 Mb/s (E1) signals from one place to another a huge amount of wires will be needed, on the other hand the SDH needs only two fibers to do the same operation. Many vendors have a product called STM1 multiplexer and its functionality to add and drop 63 × 2.048 Mbit/s into 155.52 Mbit/s (STM-1). The bit rates of the basic signals in the SDH are derived from the same clock source, which means that the SDH is completely synchronous transmission system. SDH has many different hierarchy levels starting from 155.52 Mbit/s to 10 Gbit/s and the STM-1 with a bit rate of 155.52 Mbit/s is the basic module of the SDH system. The SDH signal is terminated to E1 (2.048 Mbit/s) signals by using terminal multiplexer.Before the SDH multiplexer operates in the telecommunication market, there is a huge amount of work to put the requirements specifications, by studying the reality of the market needs. Many chip manufacturers have SDH chips in their product catalog, so one has to make a decision which manufacturer's chip to use. In addition, one must decide how to handle overhead bytes and how to implement all this in network manager software. After all these decisions, we have a huge amount of data and the last thing to do is to decide which features are implemented and which are not. Because of time-to-market pressures, the implementation has to be phased and the first phase must contain only the necessary functionality and nothing more to reduce the development time to minimum.The Synchronous Digital Hierarchy (SDH) multiplexers form the core part of the backbone telecommunication networks, and the effective design, reliability analysis and training are essential to managing SDH network effectively. Today and shortly, the demands to transfer a tremendous mass of data among the various applications in many fields inside the country become an exclusive responsibility particularly with the significant developments of the clouding policies in the different forms such the data centers and the implementations of many smart applications of the 5G in the various areas of the information technologies. The current design of the core communication network consists of 3 independent zones, the 1'st zone is layer 1 and layer 2 which recognized as the physical layer of the core optical network such Optical Transport Network (OTN), the 2'nd band is layer 3 which viewed as IP core network, and the last zone is the access and the application layers such 4G network. The challenge in the current communication model is no associations among these 3 zones of the communication network to optimize the capacities and the needed resources which are required to carry the data among any of them. Now the optical transport network (OTN) represents the critical point of carrying a tremendous amount of data for the mobile network such 4G between the different sites.

Transmission Systems Design for Wireless Applications takes you through the design and deployment of wireless transmission networks. From principles and design, to equipment procurement, project management, testing, and operation, it's a practical, hands-on engineering guide with numerous real-life examples of turn-key operations in the wireless networking industry. This book, written for both technical and non-technical professionals, helps you deal with the costs and difficulties involved in setting up the local access with technologies that are still in the evolutionary stage. Issues involved in the deployment of various transmission technologies, and their impact on the overall wireless network topology are discussed. Strategy and approach to transmission network planning, design and deployment are explored.

In the development of telecommunication networks throughout the world, digital transmission has now replaced analog transmission as the predominant choice for new transmission facilities. This trend began in the early 1960s when the American Telephone and Telegraph Company first introduced pulse code modulation as a means of increasing capacity in their cable plant. Since that time, digital transmission applications have grown dramatically, notably in the United States, Canada, Japan, and Western Europe. With the rapidity of digital transmission developments and imple mentation, however, there has been a surprising lack of textbooks written on the subject. This book grew out of my work, research, and teaching in digital transmission systems. My objective is to provide an overview of the subject. To accomplish this end, theory has been blended with practice in order to illustrate how one applies theoretical principles to actual design and imple mentation. The book has abundant design examples and references to actual systems. These examples have been drawn from common carriers, manufac turers, and my own experience. Considerable effort has been made to include up-to-date standards, such as those published by the CCITT and CCIR, and to interpret their recommendations in the context of present-day digital transmission systems.

Principles of Digital Transmission is designed for advanced undergraduate and graduate level students and professions in telecommunications. Teachers and learners can mix and match chapters to create four distinct courses: (1) a one-term basic course in digital communications; (2) a one-term course in advanced digital communications; (3) a one-term course in information theory and coding; (4) a two-term course sequence in digital communications and coding. The book provides rigorous mathematical tools for the analysis and design of digital transmission systems. The authors emphasize methodology in their aim to teach the reader how to do it rather than how it is done. They apply the fundamental tools of the discipline onto a number of systems, such as wireless data transmission systems.
