Abstract: Orthogonal frequency division multiplexing (OFDM) is used in many wireless broadband communication systems because it is simple and scalable solution to intersymbol interference caused by a multipath channel. It is used in wireless LAN and MAN applications, including IEEE 802.11a/g and WiMax. It has been adopted for terrestrial broadcasting of digital television (DVB-T) in European and Asian countries. Very recently the use of OFDM in optical systems has attracted increasing interest. At very high data rates, timing jitter is emerging as an important limitation to the performance of OFDM systems. Our work studies the timing jitter effect in detail and tries to provide simple and effective ways to deal with jitter issues on both wireless OFDM and optical OFDM systems. Further we will do some experiments about wireless and optical OFDM systems
