Xavier Fernando is a Professor at Ryerson University, Toronto, Canada, where he is serving as the Director of Ryerson Communications Laboratory. He earned his Ph.D. from the University of Calgary, Alberta, in 2001 in affiliation with TRLabs, a not-for-profit telecom research institution. He was among those who pioneered research on optical fiber-based wireless systems in the late 1990s. His Ph.D. work in this areawhere he first investigated adaptive digital signal processing (DSP) techniques for fiber-wireless (Fi-Wi) systemswon the best Canadian paper award and a US patent. He joined Ryerson University in 2001, received early tenure, and established Ryerson Communications Laboratory.

Xavier has published his research articles in multiple frontiers of Fi-Wi systems, from signal processing for (radio-over-fiber) ROF nonlinearity to microwave photonic filter design. He has received significant funding for research in this area. He has authored and co-authored close to 100 research articles and holds two patents. He is a co-author of WEBOK, A Guide to the Wireless Engineering Body of Knowledge.

Xavier was a member of the IEEE COMSOC Education Board Working Group on Wireless Communications. His work has won several awards and prizes, including the IEEE Microwave Theory and Techniques Society Prize in 2010, the Sarnoff Symposium Prize in 2009, the Opto-Canada best poster prize in 2003, and the CCECE best paper prize in 2001. He has delivered invited lectures and tutorials worldwide. He is a program evaluator for ABET and the General Chair for the IEEE Canadian Conference on Electrical and Computer Engineering (CCECE 2014). He was a member of the Ryerson Board of Governors in 20102011 and the Chair of the IEEE Toronto Section in 20122013.

Just consider how much our lives today are influenced by wireless and mobile communication technologies: from synchronized calendars to emails on the go, from simply browsing the Internet to uploading high-definition videos and photos taken with mobile phones to Facebook, from accessing maps and navigation advice to being entertained with high-definition television and videos; smart phones with mobile and Wi-Fi enable us to live our lives to their full potential. As this mobile data consumption grows and more and more machines and devices begin to incorporate the same communication platforms to achieve high-bandwidth communication via wireless channels, the networks that provide connectivity need to change by first providing more bandwidth to more users over ever growing geographic areas. The combined effect of growing data bandwidth and the ever-growing number of devices is poised to create a massive challenge in designing, building, and operating future broadband wireless access networks. Reducing the coverage of mobile networks to form small cells, shifting the carrier frequency of radio communications to high frequencies to be able to offer more bandwidths to users, and providing broadband back-haul from base stations are all needed to address this challenge. Radio over fiber (ROF) technology provides a promising technique to combine the advantage of wireless connectivity of a broadband wireless link over short distances with the bandwidth abundance of optical fiber networks in order to address these issues.

This book, entitled Radio over Fiber for Wireless CommunicationsFrom Fundamentals to Advanced Topics, is a timely introduction to this important area and the author presents it elegantly through a well-structured book. The book gradually introduces the basic concepts, moving toward a comprehensive treatment of the topicfrom transmission basics to advanced modulation methods, from optical links to wireless channels, and from linear to nonlinear impairments and mitigation strategies. Professor Xavier N. Fernando has been at the forefront of ROF research since its early stages and is definitely a leading authority on this topic. Professor Fernando has combined his in-depth understanding and long academic experience to deliver a classic book that gives us a comprehensive look at ROF technology. This book will help to inform engineers and industry practitioners, as well as researchers, with up-to-date coverage of the technology. Professor Fernando should be congratulated for writing this classic text, which I hope will provide further focus on this important technology.

First of all, thank you for buying this book. It was a very good decision. You will not be disappointed. As the name implies, the book will first provide a fundamental understanding of the topic for those who are new to it. The book then develops knowledge in advanced topics. The book is written for general communication systems engineers, who may not have detailed knowledge of photonic systems. It covers some design issues from an engineer's point of view. It also includes ongoing research and recent developments in multiple frontiers of Fi-Wi networks that will be useful for researchers and graduate students.

This book is the culmination of many years of my work in this area. Using photonic technologies for wireless communications first fascinated me during my Master's studies. I used to dream of combining the benefits of these two systems. My original idea was to stream the light wave directly from fiber (my Master's thesis was on optical-wireless communications). However, I soon realized the practical limitations of light wave propagation in air and started to research RF over fibera slightly more practical method but still with many hurdles.
