Optical Wireless Communications: IR for Wireless Connectivity – Free PDF Download
Book Description
Over the last three decades, interest in Infrared (IR) technology as a medium to convey information has grown considerably. This is reflected by the increasing number of devices such as laptops, PDAs, and mobile phones that incorporate optical wireless transceivers and also by the increasing number of optical wireless links available for indoor and outdoor use. The popularity of IR is based on the advantages it has over radio including unregulated bandwidth, immunity to radio interference, and inherent security. Optical Wireless Communications examines some of the most important features of optical wireless communication systems. It considers the benefits and limitations of IR as a medium conveying information wirelessly and compares the advantages and disadvantages of infrared to microwave and other radio systems. It also details the evolution of IR communication systems and describes atmospheric and other types of data transmission limitations. The book presents design fundamentals of optical concentrators, as well as a review of some of the most important receiver optical front-ends (containing imaging or non-imaging concentrators and optical filters), including an explanation of the different sources of infrared noise and an introduction to eye safety. It also describes optical wireless transmitter and receiver design issues, typical modulation, coding, and multiple access techniques, and introduces IrDA protocols and wireless IR networking.

Principles of Communications Networks and Systems by Nevio Benvenuto and Michele Zorzi (Eds)
Book Description
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.

Electronic Communication Systems 4th Ed. by Kennedy and Davis
Book Description
Kennedy`s Electronic Communication Systems is a classic literature on Communications. Kennedy`s book simplifies the concepts and presents the subject in as diagrammatic and theoretical manner as possible. In the adaptation, the original flavour of the text has been maintained while the old technology has been updated with the more latest ones. Due weightage has been provided to the discussion of Digital Communications, which has gained in importance since the last revision of Kennedy.

Introduction to Analog and Digital Communications by Simon Haykin, 2nd Ed
Book Description
The second edition of Introduction to Digital and Analog Communications, 2e is written at an accessible level and serves as an introductory treatment of communication theory, both ana-log and digital communications.
Given the highly mathematical nature of communication theory, it is rather easy for the reader to lose sight of the practical side of communication systems. Throughout the book, the authors have made a special effort to move through the mathe-matical treatment at an easy-to-grasp level, and also to point out the practical relevance of the theory wherever it is appropri-ate to do so. Drs. Haykin’s other text, Communication Systems reaches out to a higher level of math rigor. Also, Introduction to Digital and Analog Communications, 2e offers the probability coverage later in the book (chapter 8) since probability theory is not critical to the understanding of modulation. This also contributes to the accessible approach of the text.
Introduction to Digital and Analog Communications, 2e is self-contained and suited for a one or two-semester course in communica-tion systems taken by Electrical Engineering juniors or seniors. The book offers flexibility for organizing the course material to suit the interests of course professors and students.

Computer Networks and Internets – 5th Ed. by Douglas Comer
Book Description
Computer Networks and Internets is appropriate for all introductory-to-intermediate courses in computer networking, the Internet, or Internet applications; readers need no background in networking, operating systems, or advanced mathematics. Leading networking authority Douglas Comer presents a wide-ranging, self-contained tour of the concepts, principles, and technologies that enable today’s Internet to support applications ranging from web browsing to telephony and multimedia. This Fifth Edition has been thoroughly reorganized, revised, and updated: it includes extensive new coverage of topics ranging from wireless protocols to network performance, while reducing or eliminating coverage of older protocols and technologies. Comer begins by illuminating the applications and facilities offered by today’s Internet. Next, he systematically introduces the underlying network technologies and protocols that make them possible: low-level data communications; packet switching, LAN, and WAN technologies; and Internet protocols such as TCP, IP, UDP, and IPv6. With these concepts and technologies established, he introduces several of the most important contemporary issues faced by network implementers and managers, including quality of service, Internet telephony, multimedia, network security, and network management. Comer has carefully designed this book to support both top-down and bottom-up teaching approaches. Students need no background in operating systems, and no sophisticated math: Comer relies throughout on figures, drawings, examples, and analogies, not mathematical proofs.
