描述了一种基于光纤无线通信（ROF）的道路车辆通信系统，其中多个无线基站（rbs）通过光纤无线通信连接与控制站（CS）通信。rbs使用相同的毫米波频段与移动电台（MSs）通信。结果是一个大的虚拟细胞区，包含由一个CS控制的几个rbs。然而，在一个虚拟蜂窝带中，干扰出现在相邻蜂窝带之间的边界，因为每个区域中的基站使用相同的频带传输信号。为了尽量减少这种干扰，使用码分复用来调制在ms和rbs之间发送的信号。通过实验过程的测试表明，使用该系统可以实现最大传输速率为4.608 Mbps的无差错连续通信系统。
A radio-on-fiber (ROF) based road-vehicle communication system is described in which several radio base stations (RBSs) communicate with a control station (CS) over ROF connections. The RBSs use the same millimeter-wave frequency band to communicate with mobile stations (MSs). The result is one large virtual cellular zone encompassing several RBSs controlled by one CS. However, in one virtual cellular zone, interference arises at the bound between adjacent cellular zones because the RBSs in each zone transmit their signals using the same frequency band. To minimize this interference, code division multiplexing is used to modulate the signals sent between the MSs and RBSs. Testing using an experimental course demonstrated that by using this system, we can achieve an error-free continuous communication system with a maximum transmission rate of 4.608 Mbps.
