摘　　要：为克服传统光电探测器工作电压较高、硬件电路复杂与抗干扰能力差的问题,设计了一种基于新型氧化镓探测器的日盲紫外光通信系统。该系统在给定窗口大小的情况下,根据设计的数据处理算法对光强进行实时动态监测,通过将计算得到的阈值与光强作比较输出二值信号,结合OOK调制技术、驱动电路与非相干解调技术,实现了日盲紫外光通信系统。进一步从调制技术、驱动电路以及数据处理算法三个方面对通信系统进行仿真与实验测试,验证该系统的功能完整性、系统简洁性与可靠性。结果表明:该日盲紫外光通信系统在准确接收信号的情况下,可以直接实现将光强值转化为二值信号输出,且误码率小于10-3,能够达到简化接收端硬件电路以及提升硬件电路可靠性的目的。该系统编码简单可靠、易实现且抗干扰能力强,无需滤波装置、小巧便携、可靠性高,为日盲紫外光通信系统的优化与便携使用提供了新思路。To solve the problems of high operating voltage,complex hardware circuit and poor antiinterference ability of traditional photoelectric detectors,we designed a new solar-blind UV communication system based on Ga2O3 photodetector.The system is based on the designed data processing algorithm to monitor the light intensity in real time with a given window size,and the binary signal is output by comparing the calculated threshold with the light intensity.We also combined OOK modulation technology,driver circuit and non-coherent demodulation technology to realize the solar-blind UV communication system.Furthermore,the simulation and experimental testing of the communication system were carried out in terms of modulation technology,driver circuit and data processing algorithm to verify the functional integrity,simplicity and reliability of the system.The results show that the system can directly convert the light intensity value into binary signal output with accurate signal reception,and the bit error rate(BER)is less than 10-3,which simplifies the hardware circuit of the receiver and improves the reliability of the hardware circuit.The system is simple to encode,easy to implement and anti-jamming,freefiltering device,small and portable,and highly reliable.It provides a new solution for simple optimization and portable use of solar-blind UV communication systems.
