摘要
针对LED无线数据传输与视觉照明的双重需求,提出一种对人视觉影响较低的改进型二进制PWM调制方式PTD-PWM,分别从规则与符号结构上比较了PTD-PWM与传统PWM、OOK。从平均光功率、带宽需求及误码率等方面分析并讨论PTD-PWM的系数选择,并对PTD-PWM调制方式进行了仿真。
In view of the dual demand of LED wireless data transmission and visual lighting, this paper pro- posed a new modulation method PTD - PWM which made by binary PWM improvement has low impact on the human visual,respectively, compared PTD-PWM from the rules and structure symbol with traditional PWM, OOK, and analyzed in terms of the average optical power, bandwidth requirements and bit error rate, then discussed PTD-PWM coefficients, and carded on the simulation to the PTD-PWM modulation.
