大功率LED空间光强对VLC幅频特性的影响
Effect of high-power LED spatial light intensity on amplitude-frequency characteristics of VLC
摘要
Abstract
A VLC system transmitter and receiver based on the high-power LED army was proposed. A spatial light intensity distribution model of the LED army was established by analyzing the characteristics of LED light source. The effect of air channel distance on the amplitude-fiequency characteristics of the received signal was then studied on the basis of the established model and practical circuit testing results. Finally, it was pointed out that amplitude-frequency characteristics of VLC receiver didn't change with the spatial light intensity.关键词
