Effect of atmospheric attenuation and biosignal telemetry in free space Optical communication

Abstract

Free space optical communication uses optical beams to transmit data. In order to transmit data, line-of-sight must be maintained between the transmitter and receiver. Data rates are high, spectrum is license-free, and deployment costs are low with FSO links. However, atmospheric conditions contribute significantly to the degradation of FSO link performance. FSO systems perform differently depending on the weather conditions of a particular location. Health care monitoring is a rapidly developing network in the field of advanced medical treatment. The network combines the ideology of wireless communication, signal processing, medical information, and real-time processing units to aid the medical monitoring system. However, there are some issues that need to be resolved. Furthermore, it is challenging for learning algorithms to determine the optimal threshold value. This issue inspired the authors to create an effective de-noising technique to remove unwanted noise from these signals. The first module employs an Effect of Atmospheric Attenuation in Free-space Optical Communication Coastal Environment. The impact of environmental factors like snow, rain, haze, fog, and dust on the efficiency of optical wireless communications using a free space optical system. It takes into account atmospheric attenuation in various weather scenarios for free space optical links, taking visibility and operating wavelengths into account. The Optimized Lipschitz Function (OLE) before transmitting over the FSO medium for coastal regions.In this technique, the OLE function measures the informative data from the atmospheric channels. On the receiver end the system consists of an optical filter, FDM, de-multiplexer for retrieving the electrical form. The proposed models have strong validation over the wide range of temperature and humidity over the FSO connection in an environment with coastal regions. newline
