![]() ![]() Visually identical transmitted and received signals also validate the accuracy of the simulation results when compared to those obtained from the real-time FSO-SDR communication system. FSO (free space optics) is an optical communication technology in which data is transmitted by propagation of light in free space allowing optical connectivity. We demonstrate successful transmission and reception of baseband signals with very low bit error rate. ![]() A fully-functional optical communication link has been accomplished using the Universal Software Radio Peripheral (USRP), MATLAB-Simulink communication toolbox and hardware support package, Laser diode, and a Photodetector. This system can be used for communication purpose in hours and in lesser economy. It is a promising communication technique that has. Medium can be air, outer space, or vacuum. Free space optical communication (FSO) was developed in response to the increase in demand for high speed and tap-proof communication system 1. In this thesis work, we implemented a real-time FSO communication system using an SDR platform. FSO is a communication system where free space acts as medium between transceivers and they should be in LOS for successful transmission of optical signal. When integrated with the FSO system it opens a plethora of opportunities since the Visible Light Frequency Spectrum is barely occupied by the existing technologies and can be designed cost-effectively for the vast bandwidth it has to offer. Taysir Nayfeh, for affording me the opportunity to pursue my education through working at the Industrial Space Systems Laboratory, and for helping me develop my. Laser transmitters, at wavelengths some 10,000 times shorter than RF waves, result in beams that are far narrower for the same unit aperture sizeproviding more concentrated communications power at the receiver with lower required. Reprogrammable FPGA-based Software Defined Radio (SDR) technology is deployed as a feasible solution to this problem since they can be reconfigured simultaneously realizing the user requirements. Free-space optical communication (FSOC) using lasers offers the promise of breaking through that RF bottleneck. It is also expensive to upgrade to the emerging new standards such as 5G New Radio (5GNR) by substituting the existing hardware resources. Free space optical communications use laser transmission through the air to communicate wirelessly between two locations. The conventional single-purpose dedicated hardware resources in the telecommunication systems have significant limitations since they provide a single communication service using a specific standard at a time. Next-generation software-defined free-space optical (FSO) communication systems may substitute many conventional radio communication systems. ![]()
