“…However, in many practical applications the transmitted beam can be approximated by the circularly symmetrical intensity distribution, where θ x = θ y = θ and also w x = w y = w. Then, simplified calculation (5) of power P RX at the receiver plane can be used instead of more complex one for elliptically symmetrical beam [6].…”

In the paper, an optical wireless link for point-topoint communication is analyzed. Its main focus is the analysis of the influence of various misalignments on the received power. Analysis includes influence of the tilt of the transmitter and the receiver as well as their mutual misalignment respecting the Gaussian intensity distribution of the transmitted beam in terms of geometrical optics. As a result of the analysis, expression for influence of the various misalignments on the received power are presented. For the simulation of the link, a MATLAB environment was used. The conclusion contains synthesis of the simulations results. The main contribution is in consideration of the Gaussian beam distribution of the transmitted beam and its analysis for precise prediction of geometrical losses for individual free-space optical links.

“…In [5], a link budget analysis for free-space short-range optical links was presented, but the system was using laser which features excellent directivity and is quite different from visible light. In [6], a line-of-sight (LOS) VLC system design was demonstrated, where considerable details such as the channel model, the transmitter (TX) and the RX were included.…”

This paper presents the complete link budget analysis of a VLC system. By calculating the transmitter's emitted power, the channel path loss and the receiver's input referred noise, the system SNR and BER performance are derived. Furthermore, a VLC transceiver system is implemented with the analog front-end using discrete components while the baseband in FPGA, and the experimental results demonstrate that the measured BER agrees well with the calculation.Index Terms -Bit error rate, light emitting diodes, link budget analysis, photodiode, visible light communication.

The development of semiconductor technology has led to an increase of the usable bandwidth of light-emitting diodes (LED), which are suitable for indoor high-speed communications or free-space optical (FSO) communications over a relatively short distance. The high-speed long-distance FSO links, where turbulence effects are considerably high, are a domain of laser sources. Hence, the paper covers the study of an exact analytical model of FSO link attenuation and the benefits of using an elliptically symmetrical Gaussian beam rather than a circularly symmetrical one.The paper further generalises the study to the FSO link misalignment and the pointing error analysis. The main contribution is in the derivation of an exact laser beam attenuation model, which is further used to analyse the geometrical losses in FSO systems as well as a general misalignment of an elliptically symmetrical beam in any direction from a circular receiver aperture. The challenging mathematical part includes two and six expressions of the general laser beam attenuation model for FSO communications taking into consideration circular and elliptical beams, respectively. The paper concludes with an analysis of advantages of using elliptical beams in FSO systems and a discussion on optimal orientation of the major beam axis with respect to the maximisation of the link availability.The paper summarises some previous results of the team of authors to further extend the model's applicability into more general terms towards a unified model.
