Study Of RoF Application In Intelligent Transportation System

Intelligent transportation system is an important means to solve the traffic jam, reduce the number of traffic accidents, and ensure the traffic operation in high-speed today in China. Radio-over-Fiber (RoF) communication technology is a kind of broadband wireless access technology, very suitable for the intelligent transportation system(ITS).This paper mainly studies the application of millimeter-wave RoF in ITS. First, we analyze the hardware configuration of baseband,intermediate frequency and radio frequency RoF in detailed, and compare the transmission performance by using the OptiSystem optical design software; then we optimize the layout of RoF base station in ITS in order to obtain the biggest coverage by choosing the proper space between stations; Finally, we take code division multiplexing(CDM) technology into ITS in order to avoid the effects of frequent switching, the same frequency interference and doppler frequency shift etc, and verify the feasibility of this technology by using OptiSystem and MATLAB mixing programming. The research result of this paper provides a theoretical reference to RoF application in ITS.
