基于BPPM调制的非直视紫外光通信在异步周期脉冲干扰下的性能分析OA
Performance analysis of BPPM-based NLOS UVC system under asynchronous periodic pulse jamming
随着紫外光通信技术在无人机平台上的应用,对地面非直视紫外光通信系统带来潜在威胁.针对基于二元脉冲位置调制(Binary Pulse-Position Modulation,BPPM)的非直视紫外光通信系统,首先推导了在异步周期脉冲干扰下BPPM符号的两个时隙中干扰信号的联合概率质量函数.进一步推导了系统平均误码率和可达速率的理论闭合表达式,并使用蒙特卡洛仿真对理论结果进行了验证.最后,给出了在不同干扰距离、发射端峰值光功率以及干扰脉冲参数下的性能结果.结果表明,相较于开关键控,非直视紫外光通信系统采用BPPM可以获得更加优异的抗干扰性能.
As the application of ultraviolet communication(UVC)technology on unmanned aerial vehicle platforms expands,ground-based non-line-of-sight(NLOS)UVC systems face potential jamming threats.Focusing on NLOS UVC systems that employ binary pulse-position modulation(BPPM),this paper derives the joint probability mass function of jamming signals of two slots in a BPPM symbol under asynchronous periodic pulse jamming.Then,theoretical closed-form expressions for the average bit error rate and achievable data rate are obtained and validated through Monte Carlo simulations.Finally,system performance is evaluated under varying jamming distances,transmitter peak optical powers,and parameters of jamming pulses.The results show that,compared with on-off keying,BPPM offers significantly improved anti-jamming performance in NLOS UVC systems.
