摘要
数字集群移动通信系统相比模拟集群其频谱利用率和信号抗信道衰落的能力都有很大的提高.利用现有设备i30SX数字集群手机和DGPS-220等进行集成,设计的一种可用于公交车、出租车等车辆系统的车载台,既可以定位,又可以进行调度,且成本也较低.结果表明,此设计基本上达到了预期的目标.
Compared with the simulated cluster systems, the efficiency of spectrum and the anti-feding ability of signal have been much improved in the digital cluster systems. This paper propo＇s a low-cost platform in bus and taxi by integrating the available apparatus of i30SX digital cluster mobile phone and DGPS-220, which can finish two tasks： positioning and scheduling. The result shows that the anticipated aim is basically achieved.
