Free space optical (FSO) communication provides the capacity to deliver high-speed digital data links into the far off and rural factions where topography, setup cost or groundwork safety pose acute barriers to deployment. The challenges in any FSO system are the transmission impairments and space loss which deteriorate the link performance. This a...
We propose a novel design of orthogonal frequency division multiplexing-mode division multiplexing (OFDM-MDM) based radio over free space optical (RoFSO) transceiver under the dust effect. Two separate 20 Gbps-40 GHz 4-QAM data bearing optical beams are transported over two distinctive Hermite-Gaussian modes; HG00 and HG01, of a single-frequency la...
The increasing demand for high-speed information transmission as a result of adoption of wide variety of multimedia applications including high-definition television, social networking, and live streaming etc. has challenged the service providers. The conventional wireless transmission systems based on radio frequency are unable to meet the high ch...
This paper investigates the feasibility of using free space optics (FSO) for communication between multiple hovering unmanned aerial vehicles (UAVs) and a detection unit (DU) in the Arctic. The uniqueness that sets apart UAV-based FSO systems from conventional FSO systems is the dynamics of the system since location and inclination of the UAV chang...

This paper presents a novel 160 Gbps free space optics (FSO) communication system for 6G applications. Polarization division multiplexing (PDM) is integrated with an optical code division multiple access (OCDMA) technique to form a PDM-OCDMA hybrid. There are two polarization states: one is X-polarization generated from adjusting the azimuthal angl...
We design and demonstrate a coherent optical wireless communication link for data center interconnections and 5G services in smart cities. The adoption of a single modulated laser scheme as optical transmitter and homodyne detection-based receiver guarantees conceptual simplicity for the optoelectronic subsystems of this optical backhaul network. T...
Mode division multiplexing (MDM) is an emerging information transmission technique in which multiple data signals can be transmitted simultaneously on different modes of a single wavelength laser beam over a free-space channel. MDM is a potential technique for the realization of high-speed spectral efficient communication links for future generatio...
The requirement of high data rate information transmission is rising exponentially for supporting different services including social networking, web streaming, and biomedical sensor data transmission. Such services required high channel bandwidth with secure information transmission and immunity to electromagnetic interference. Radio over free spa...
Internet of things witnessed rapid growth in the last decade and is considered to be a promising field that plays an all-important role in every aspect of modern-day life. However, the growth of IoT is seriously hindered by factors like limited storage, communication capabilities, and computational power. On the other hand, cloud has the potential...
The evolving expertise in optical wireless communication (OWC) and free space optics (FSO) proposes numerous benefits above conventional radio network owing to unlicensed bandwidth, low installation time, affordable cost, high data rate and insusceptibility to electromagnetic interference. In this paper, two wireless optical communication systems a...
Free space optics is a light-wave communication technology that operates in the near-infrared region of the electromagnetic spectrum (about 700-1675 nm) and uses atmospheric channel as the transmission medium for both inter-satellite and terrestrial networks. However, the operational proficiency of free space optical communication system is highly...
In this work, we propose the design and analysis of polarization division multiplexed M-ary modulation-based free-space optical (FSO) transceiver using balanced homodyne detection (BHD) and digital signal processing (DSP) at the receiver end. We have employed DP-QPSK, DP-16-QAM, and DP-256-QAM optical modulation techniques to gain greater spectral...
