A comprehensive evaluation of Fi-Wi, enabling readers to design links using channel estimation and equalization algorithmsThis book provides a detailed study of radio over fiber (ROF) based wireless communication systems, otherwise called fiber wireless (Fi-Wi) systems. This is an emerging hot topic where the abundant bandwidth of optical fiber is directly combined with the flexibility and mobility of wireless networks to provide broadband connectivity. Its application is increasing because of the growing demand for broadband wireless services. In such a system the transmission of the radio signals over a fiber is an important task. This book provides substantial material on the radio over fiber part of the complete fiber-wireless system, including new research results on the compensation methods.The early chapters provide fundamental knowledge required for a non-expert engineering professional as well as senior/graduate level students to learn this topic from scratch. The latter part of the book covers advanced topics useful for researchers and senior students. Therefore, this book provides a comprehensive understanding of the system for readers who will gain enough knowledge to design Fi-Wi links of their own by learning how to develop Fi-Wi channel estimation and equalization algorithms. This concept is completely novel in current literature and has been patented by the author.Readers are expected to have a basic understanding of fiber optics and wireless communications to easily follow the book and to appreciate the concepts. Basics of the Fi-Wi system and signal processing approaches are clearly explained. It covers a multidisciplinary topic and acts as a bridge between optical and wireless communication domains. In the increasingly demanding telecommunications profession, engineers are expected to have knowledge in both optical and wireless communications and expected design combined/hybrid systems.

Xavier Fernando, Professor and Director, Ryerson Communications Laboratory, Department of Electrical and Computer Engineering, Ryerson University, Toronto, Canada.Xavier Fernando has been working Fi-Wi systems for over 15 years. He did his PhD in this area at the University of Calgary in affiliation with TRLabs. His PhD work has been patented and won the Canadian best paper award in 2001. He joined Ryerson University in 2001 where now he is a full professor. Professor Fernando is an IEEE Communications Society Distinguished Lecturer and the Chair of the IEEE Toronto Section, Canada. He has been working in multiple aspects of wireless communications, having a special interest in radio over fiber systems. He has delivered invited talks worldwide including at the Cambridge University (UK), National Research Council (Canada), Athens Institute of Technology (Greece), Indian Institute of Science (India) and Princeton University (USA) on radio over fiber systems. He has co-authored close to 100 research articles, two patents and few non-disclosure agreements.
