摘要
通信车集成有多种无线通信设备,这些设备间的杂散干扰导致了接收灵敏度的恶化,接收灵敏度的恶化将导致通信覆盖距离的缩小。分析了杂散干扰对接收机灵敏度的影响,并提出了解决方案,实例表明,文中所提方案可减少集成过程中杂散干扰对无线通信性能的影响。
There are a variety of wireless communication equipments in emergency communication vehicles. The spurious interference between devices leads to the deterioration of the receiver sen- sitivity. The deterioration reduces communication coverage. Effects of spurious interference on receiver sensitivity are analyzed. Practical applications show that the method can reduce the ef- fects of spurious interference on the wireless communication performances in the integration pro- cess.
