Abstract
The radio-over-fiber (RoF) network has been a proven technology to be the best candidate for the wireless-access
technology, and the orthogonal frequency division multiplexing (OFDM) technique has been established as the core
technology in the physical layer of next generation wireless communication system, as a result OFDM-RoF has drawn
attentions worldwide and raised many new research topics recently.
At the present time, the trend of information industry is towards mobile, wireless, digital and broadband. The next
generation network (NGN) has motivated researchers to study higher-speed wider-band multimedia communication to
transmit (voice, data, and all sorts of media such as video) at a higher speed. The NGN would offer services that would
necessitate broadband networks with bandwidth higher than 2Mbit/s per radio channel. Many new services emerged,
such as Internet Protocol TV (IPTV), High Definition TV (HDTV), mobile multimedia and video stream media. Both
speed and capacity have been the key objectives in transmission. In the meantime, the demand for transmission
bandwidth increased at a very quick pace. The coming of 4G and 5G era will provide faster data transmission and higher
bit rate and bandwidth.
Taking advantages of both optical communication and wireless communication, OFDM Radio over Fiber (OFDM-RoF)
system is characterized by its high speed, large capacity and high spectral efficiency. However, up to the present there
are some problems to be solved, such as dispersion and nonlinearity effects. In this paper we will study the dispersion
and nonlinearity effects and their elimination in OFDM-radio-over-fiber system.
