| Research Abstract |
In this research, a frequency sharing with OFDMA is considered to be applied on road to vehicle communication (RVC) and inter-vehicle communication (IVC). In such spectrum sharing systems, a synchronization error leads to degrade the orthogonality among OFDMA subcarriers and the performance of RVC is degraded. This paper proposes a frequency sharing scheduling to suppress the interference to RVC by selecting subcarriers and controlling power at IVC adaptively during the period allocating the time slot and the subcarrier of OFDMA to multiple pairs of RVC and IVC, respectively.
