Optimal LED placement in indoor VLC networks

Optimal Precoder for MIMO Schemes in Indoor Wireless VLC Systems

In multiple-input multiple-output (MIMO) indoor visible light communication (VLC) systems, channel gains are highly correlated. As a result, the bit error rate (BER) of the system is degraded. To improve the BER performance of the system, we propose two precoders, namely, an optimal precoder and a diagonal precoder for MIMO schemes in VLC systems with Nt light emitting diodes (LED) and Nr photo...

LAT Indoor MIMO-VLC

Visible Light Communications (VLC) is an innovative technology that uses the visible spectrum for high-speed data communications. In this paper we investigate the use of MIMO in the design of luminaires supporting VLC and, specifically, in enabling localization and high data rate services. Localization and transmission appear as two different problems in the communication system; however, the f...

Optimal Placement and Sizing of Distributed Generations in Unbalanced Distribution Networks Considering Load Models and Uncertainties

Development of distributed generations’ technology, trends in the use of these sources to improve some of the problems such as high losses, low reliability, low power quality and high costs in distributed networks. Choose the correct location to install and proper capacity of these sources, such as important things that must be considered in their use. Since distribution networks are actu...

Optimal capacitor placement in distribution networks

This paper deals with the voltage stability problem associated with radial distribution networks. Two load models are studied: the full load flow model (FLFM) and the equivalent generic single-line model (EGSLM). Optimization is then carried out to find the optimal capacitor size that minimizes some costing function, and finally several capacitor placement techniques are studied.
