Abstract:

Considering model dispersion and nonlinear in multimode fiber(MMF),MB-OFDM UWB technology was fused into MMF communication system.Through the analysis of a distinguishing feature of MB-OFDM UWB signal and model dispersion in MMF,it was proved that MB-OFDM UWB technology had the ability to overcome multimode fiber mode dispersion.Peak average power ratio(PAPR) of MB-OFDM UWB signal and the PAPR reduction method were researched.The simulation platform was established by MATLAB and Optisystem software,verifying the ability to overcome modal dispersion in MB-OFDM UWB MMF communication system and the improvement in system performance by the PAPR reduction method.

Key words: communication, multi-band orthogonal frequency division multiplexing ultra wideband(MB-OFDM UWB), multimode fiber(MMF), mode dispersion, peak average power ratio (PAPR)
