摘要
预加重作为解决发射端LED调制带宽限制问题的技术，在以往的研究中存在电路设计复杂、功耗大且效率低的问题.针对上述问题，本文从频域分析角度出发，基于预加重技术的原理提出了分频预加重电路，通过仿真与实验实现分频预加重电路并与预加重电路进行对比验证.仿真与实验表明，所提出的分频预加重方案在可见光通信中实现了与预加重电路相同的频率响应补偿效果，有效降低了驱动电路的复杂度和功耗.证明了分频预加重技术在基于可见光通信的LED驱动电路中实现低功耗集成的可行性.
Abstract
As a technology to solve the problem of transmitter LED modulation bandwidth limitation
there are complex circuit design
high power consumption and low efficiency in previous studies.In view of the above problems
from the perspective of frequency field analysis
the frequency division pre-emphasis (FDPE) circuit is proposed based on the principle of pre-emphasis (PE) circuit
and finally realizes the FDPE circuit through simulation and physical design and compares with the PE circuit.Simulation and experimental data show that the FDPE circuit proposed in this paper achieves the same frequency response compensation effect as in the PE circuit in visible optical communication
effectively reducing the complexity and power consumption of the driving circuit.It is shown that the split-frequency advance the feasibility of achieving low power integration in LED driven circuits based on visible optical communication.
