Chapter 11 OFDM Applications in Access Optical Networks

Orthogonal frequency-division multiplexing (OFDM) as a technology that enables robust transmission over both wireless and optical channels has already been employed in many communication standards, including wireless local area network (LAN; also known as Wi-Fi), digital video and audio broadcasting standards, digital subscribed loop (DSL), and Worldwide Interoperability for Microwave Access (WiMAX, or IEEE 802.16).

In this chapter, we describe the use of OFDM in radio-over-fiber (RoF) systems, passive optical networks (PON), WiMAX, ultra wideband (UWB) communications, and for indoor wireless optical applications.
