This article presents the concept of deploying Software Defined Radio (SDR) for laser beam modulation in Optical Wireless Communication (OWC). To achieve modulation and demodulation of the beam generated by Laser Diodes (LDs). SDR is used to provide a sophisticated and flexible possibility of readjustment without deeper intervention into the electronics of the OWC connection. To make conclusions regarding...
This article explores the influence of the concentrated carbon dioxide (CO2) gas on the different Phase Shift Keying (PSK) modulations used for Optical Wireless Communication (OWC) links. In this work, the OWC consisted of a laser diode, a photodetector, and a transmission medium. The Universal Software Radio Peripheral (USRP) unit created and evaluated the PSK modulations. This unit modulated the...
