چکیده

The widespread deployment of white light-emitting6 diodes (LEDs) for illumination provides a unique opportunity to create flexible, accurate, and ubiquitous indoor communication positioning system. In this paper, we exploit the location information obtained via LEDs improve performance an visible light (VLC) Specifically, propose optimal LED power management framework maximize average data rate across room while satisfying bit error (BER) constraint room. maximum allowed localization error, as function number blockages irradiance angle, have been calculated. addition, closed-form expression BER is derived proposed allocation scheme. We also formulated optimization problem that will savings among with respect permissible in localization. It has shown that, by employing results significant amount power-saving, which approximately 40% 4 configuration 70% 26 8 compared equal allocation. Further, found out be 28 7 cm 18 LEDs, respectively, 29 achieve achievable rate. Finally, it 30 dimming range up can achieved

Indoor Location Estimation Using Visible Light Communication and Image Sensors

High power white LEDs are expected to replace the existing lighting technologies in near future which are also suggested for visible light communication (VLC). We proposed an algorithm for high precision indoor positioning using lighting LEDs, VLC and image sensors. In the proposed algorithm, four LEDs transmitted their three-dimensional coordinate information which were received and demodulate...

LED Modulation Characteristics in a Visible-Light Communication System

This paper conducts a research on modulation characteristics of blue light-emitting diodes (LEDs) used in a visible-light communication (VLC) system. Through analysis of the modulation characteristics of LEDs with different emitting sizes, we find that there is a similar linear relationship between LED’s 3dB bandwidth and the operation current density. This experiment also shows that high serie...

Power Distribution Investigation of a Diffused Cellular Indoor Visible Light Communication System

This paper presents a three dimensions (3D) model of optical power distribution in a diffused cellular indoor visible light communication (VLC) system. To achieve an ideal system which has a maximum coverage area with a minimum power consumption, both hexagon geometric structure and holographic light shaping diffuser (LSD) are employed. We analysed the mathematical models for both square and he...
