随着高速移动的数据需求的不断增长和智慧城市的愿景,光无线,也就是自由空间光(FSO)通信由于其显著更快的数据传输速率、更高的安全性、更低的成本和减少的功率使用而被认为是关键技术。这些有益的效果已经引起了人们对探索用于移动的平台的FSO技术的兴趣,例如基于无人机的蜂窝塔,以向偏远地区提供互联网服务,或者甚至用于在战场上具有堵塞的无线电信道的地面上的无线通信。为了建立安全的定向FSO通信(FSOC)链路,需要采用直接视距(LOS)技术,但FSOC链路对移动的节点的随机和不稳定运动以及自由空间介质中的湍流非常敏感。通过设计能够进行带内全双工(IBFD)通信的基于激光的收发器的多元件平铺,可以改善FSOC链路的性能。在这项工作中,我们提出了一个遗传算法框架,探索优化的多元素FSO收发器平铺模式,以确保最大的信号干扰噪声比(SINR),并尽量减少振动的移动的平台和大气湍流的影响。
With ever-growing demand of high-speed mobile data and in vision of smart cities, optical wireless, a.k.a. free-space optical (FSO), communication deem to be a critical technology due to its significantly faster data transfer rate, higher security, lower costs, and reduced power usage. These beneficial effects have led to interest in exploring FSO technologies for mobile platforms such as drone-based cell tower to provide Internet services to remote areas, or even for wireless communications on the ground with jammed radio channels as in battlefields. Direct line-of-sight (LOS) is required to establish secure directional FSO communication (FSOC) links which are highly susceptible to random and erratic movements of the mobile nodes as well as the turbulence in the free-space medium. The performance of FSOC links can be improved by designing multi-element tiling of the laser-based transceivers which is capable of in-band full-duplex (IBFD) communication. In this work, we propose a genetic algorithm framework to explore optimized multi-element FSO transceiver tiling patterns to ensure maximal signal-to-interference and noise ratio (SINR) and minimize the effects of vibration of the mobile platform and atmospheric turbulence.
