In digital communication systems, information is transmitted in a series of code sequences; the receiver must know the starting and ending time of each code, so it needs to have a bit timing pulse sequence for the sampling decision, which has the same repetition frequency as the code rate of transmitting end and the same phase as the optimal decision time. Companies have understood that an intelligent communication direction is translated into worth for the corporate wherever the quality that is, folks are concerned and flow in production processes with higher quality, the culture and values of the corporate square measure reinforced. The corporate and of course directly affect the productivity and economic performance of it. The role of Communication grows as communication of the companies has increased its importance and its role, which are located at the first executive level.

This book provides an outline of the analysis and design of digital communication systems. It provides wide-ranging coverage of the essential principles, techniques, and tools of Digital Communications. This book opens with a focus on the improved design of bit synchronization clock extraction in the digital communication system. In the last few years, worldwide interoperability for microwave access (WiMAX) has been proposed as a promising wireless communication technology due to the fact that it can provide high data rate communications in metropolitan area networks (MANs). Until now, a number of specifications for WiMAX were standardized by the IEEE 802.16 working group. In this book, the architecture of the WiMAX core network, all-IP mobile network, and optical integrative switching are introduced. It also tells the accounting of WiMAX in detail. It presents a critical approach to the null convention floating-point multiplier. Next, this book explores the communication basics and methodologies of networked control systems. It also presents a comprehensive approach to reduced ecological footprints of modern facilities introducing the implementation of advanced wireless technologies, and human resources’ benefits; new wideband notch antennas for communication systems; and performance evaluation of scheduling algorithms for 4G (LTE). Lastly, the book closes focusing on a simulation technique for wireless mesh networks to present its topology and evaluate its impact on the communication revolution. The book covers both the hardware and software concepts ideal for engineers and practitioners that are working in the field of digital communication system design.
