摘要：
In this paper, an indoor VLC system based on new LED array arrangement using 16 LEDs distributed in a 3-D space around the ceiling is presented. The proposed designs performance are investigated and compared with other different designs [8, 9] using the same number of LED arrays. Enhance received power, data rate and SNR across the room without increasing number of LEDs arrays is our purpose. To evaluate the system performance, the received power and SNR were calculated. While to analyze the impact of inter symbol interference the root mean square delay spread was calculated too. The results show that a significant improvement was observed in all the parameters for evaluating the performances of the proposed system, in particular (received power, SNR, RMS and data rate). The received power under our proposed models was increased from 2.1666 to 2.5804 dBm for model 1, and 0.0592 to 0.7787 dBm for model 2. The SNR is increased from 73.987 to 74.5765 dB for model 1, and 69.8918 to 70.8576 dB for model 2 and the data rate is enhanced as well from 116.90 to 139.4031Mb/s for model 1, and from 125 to 167.7283 Mb/s for model 2.
