紫外通信接收预处理系统研制

为提升紫外通信在较远距离的信息接收能力,针对接收端光信号转换为微弱电信号的特点,结合解调方案对信号的处理要求,设计了具有选频、放大功能的预处理系统。选用低噪声器件,采用低噪声化设计方案。结合复杂电磁环境的通信需求,考虑了抗干扰措施。利用Multisim对电路进行设计和仿真,对硬件电路进行了实验测试。结果表明,该预处理系统能够满足在较大距离上进行通信的需要。

Design of pretreatment system in UV communication receiver

To improve the performance of UV communication in a quite large range,according to the characteristics of weak signal conversed from light and the demodulation method,a pretreatment with amplifier and filter was designed.Instruments with ultra low noise were applied.To use the system in complex electromagnetic environment,some anti-jamming measures were considered.The circuit was designed and simulated by Mutisim.Tests to the hardware were did.The requirement to communicate in a quite large range can be sat...
