Abstract (in Japanese) (See Japanese page) 
(in English) The IVC systems based on CSMA/OFDM scheme such as IEEE802.11p or ARIB STD-T109 in Japan are widely developed because autonomous distributed networks are easily made by using the CSMA/CA MAC pro- tocol. However, the hidden terminals in CSMA networks cause the performance degradation. In our previous study, a new IVC scheme using CDMA had been proposed to mitigate the impact of hidden terminals and evaluated the performance in the simple straight road model. However, performances of both IVC schemes are not evaluated in the urban area road model assuming multipath fading. In this paper, performances of the DS-CDMA IVC scheme and CSMA/OFDM IVC scheme are evaluated in urban area road model. As the results of simulations, it was confirmed that the PER (Packet Error Rate) performances of CSMA/OFDM IVC can be made better than the DS-CDMA. On the other hand, DS-CDMA shows the possibility that it is able to achieve a low delay communication as compared with CSMA/OFDM.
