摘要：

The inter-vehicle communication (IVC) systems are based on carrier sense multiple access/orthogonal frequency division multiplexing (CSMA/OFDM) scheme. However, it is concerned that the delay time increases significantly as the number of vehicles increases. In order to reduce the effects of this problem, research has been conducted on simultaneous communication using direct spread-code division multiple access). However, there is concern that the communication performance of applying this scheme is degraded by different and same intersymbol interference (ISI). This paper proposes schemes to reduce two types of ISIs and shows the performance is improved by the proposed method.
