In this present technology, scientists have taken the maximum effort of research on UWB signals, which is useful in the field of the sensor networks and wireless data network access. UWB provides high speed data communication without compromising frequency band. The major limitation in the UWB systems had to encounter with interferences with narrow frequency band levels. Multiband orthogonal frequency division multiplexing ultra wideband (MB-OFDM UWB) generates a 60 GHz signal. In next generation wireless technologies, they are making use of millimeter waves (unlicensed band) for transmitting instead of microwave in order to avoid interference and absorption or loss of signal. In this paper MB-OFDM based UWB for millimeter wave propagation over optical fiber transmission system is proposed and analyzed using MATLAB.
