Diffraction Effects and Optical Beam Shaping in FSO Terminals,a lens socket. An elliptically symmetrical Gaussian beam is considered in the analysis to improve the generality and to analyze beams produced by edge-emitting semiconductor lasers. From the Huygens-Fresnel principle, two models of the Fresnel diffraction were derived. These models provided means fo

Information Theoretical Limits of Free-Space Optical Links,lso allows its utilization for further performance analysis of various types of wireless communication systems. Under the umbrella of generalized fading channels, a unified ergodic capacity analysis of a free-space optical (FSO) link under both types of detection techniques (i.e., intensity modulati

Performance Analysis of FSO Communications Under Correlated Fading Conditions, channels. To do this, we firstly describe in detail the . model and explain how to model space-diversity FSO channels. Next, we investigate the fading correlation existing in real space-diversity FSO systems using wave-optics simulations. To integrate the fading correlation into the . channel model

OFDM-Based Visible Light Communications,ns. The principals of OFDM techniques for intensity modulation and direct detection (IM/DD) systems are explained in detail in Dimitrov and Haas, Principles of LED Light Communications: Towards Networked Li-Fi, (2015) [.]. A number of inherently unipolar OFDM techniques were recently proposed as pow

Block Transmission with Frequency Domain Equalization for VLC,s. They employ an inverse fast Fourier transform (IFFT) at the transmitter and a fast Fourier transform (FFT) at the receiver, whereas the data symbols are processed block-wise. Pulse-amplitude modulation (PAM) or single subcarrier (SSC) modulation combined with block transmission and frequency doma

Satellite Downlink Coherent Laser Communications, information systems in space. There is growing interest in the high sensitivity and spectral efficiency of coherent optical receivers for downlink systems, despite a higher cost and complexity than direct-detection receivers. In practice, however, when the link passes through the atmosphere, clear-

Cooperative Visible Light Communications,onsidered with two light sources; the one at the ceiling is connected to the backbone network and provides ambient light to the environment while the other one is mounted on the desk and used for task lighting. The system architecture builds upon DC-biased optical orthogonal frequency-division multi

Coded Orbital Angular Momentum Modulation and Multiplexing Enabling Ultra-High-Speed Free-Space Opttal angular momentum (OAM)-based modulation and multiplexing for ultra-high-speed optical transmission over free-space optical (FSO) links. OAM is associated with the azimuthal phase dependence of the complex electric field. Because its eigenvectors are orthogonal, they can be used as basis function
