Chapter 7 Various Types of Optical OFDM

7.1 Introduction

One of the major strengths of the orthogonal frequency-division multiplexing (OFDM) modulation format is its rich variation and ease of adaption to a wide range of applications. In wireless systems, OFDM has been incorporated in wireless local area network (LAN; IEEE 802.11a/g, better known as Wi-Fi), wireless WAN (IEEE 802.16e, better known as WiMAX), and digital radio/video systems (DAB/DVB) adopted in most areas of the world. In RF cable systems, OFDM has been incorporated in ADSL and VDSL broadband access via telephone copper wiring or power line. This rich variation results from the intrinsic advantages of OFDM modulation, including dispersion robustness, ease of dynamic channel ...
