| Abstract(in English) | In the road to vehicles communications of the ITS(Intelligent Transport Systems), the received signal suffer a frequency selective fading because of high bit rate transmission. This study focuses on the application of OFDMtechnique to the road to vehicles communications, which is one of the anti-multipath fading modulation techniques. In the ITS, when multi-casing communication systems are employed to avoid the influence of shadowing, it sometimes happens that the some transmitted signals cancel each other when the relative phase is around π. In this study, we investigate PER performance when the transmitted timings from the two transmitters are varied under the repeated transmission environment. From the simulation results, it is shown that PER performance with the varied timings is improved in comparison with that with the same timings. |
