Abstract

The benefits of Free space Optics (FSO) motivates to use it for future high data rate demanding communication applications. However, widespread growth of the technology has been hampered by reduced availability due to weather influences on the link. The alternate is to use back up RF link for improving the availability. But it requires intelligent switching back and forth between two links. The forward prediction of the received signal strength can greatly improve the performance of such hybrid network. The forward prediction approach has been analyzed using measured FSO attenuation data. The results are analyzed in terms of mean square error.

FSO/RF混合网络中FSO接收信号的正向预测
自由空间光学(FSO)的优点促使人们将其用于未来高数据速率要求的通信应用。然而,由于天气对链路的影响,可用性降低,阻碍了该技术的广泛发展。另一种方法是使用备用射频链路来提高可用性。但它需要在两个链接之间智能地来回切换。对接收信号强度的前向预测可以大大提高混合网络的性能。利用实测的FSO衰减数据对正演预测方法进行了分析。结果用均方误差进行了分析。
