摘要
分析了OBU设备质量指标,提供了一种基于集成芯片的高可靠性OBU解决方案。详细阐述了OBU的窄带接收、双信道自适应、频率稳定性、天线和灵敏度等设计方法以及OBU功耗分析,理论设计和实际测试表明,基于该方案的OBU产品具有相当好的一致性、稳定性和可靠性,代表了OBU的主流发展方向。
The OBU quality indexes in specification were analyzed,a reliable solution to OBU based on integrated circuit was provided.The design method of OBU's narrowband signal receiving,two-channel adaptive receiving,stability technology of carrying wave,antenna designing and the sensitiveness designing as well as OBU's power consumption were presented.The design and test prove that the OBU product based on the presented scheme possesses the advantages in the respects of consistency,stability and reliability,etc.which represents the OBU's' mainstream.
