新型LED阵列分布的室内可见光通信系统模型研究
Research on Model of Indoor Visible Light Communication System with Novel LED Arrangement Pattern
摘要
Abstract
By analyzing the indoor Visible Light Communication system commonly used LEDs illumination radiation, this paper investigates a circle-corners compensated distribution scheme of the LEDs. Our studies show that the the SNR fluctuation under such an arrangement can reduced 90% which guarantees that users can obtain almost identical communication quality within better entire light intensity distribution. We use Root-Mean-Square delay spread to simulate the multipath delay which has reflections, then we investigate a more realistic channel model using Zero Forcing Equalization. Although the distribution scheme increasing the inter-symbol interference(ISI), the bit error rate(BER) is also very close to that channel without any ISI in the system. The scheme and the channel model reflect the actual needs of multi-user in VLC which has broad prospects for application.关键词
