摘要

光保真(Li-Fi)创新是一种无线通信(WC)系统，依赖于紫光(800太赫兹)和红光(400太赫兹)之间的可察觉光的利用。不像Wi-Fi利用电磁范围的无线电部分，Li-Fi利用光学范围，例如电磁范围的明确的光部分。Li-Fi的指导原则是通过光源的丰度调整以一种良好的、制度化的方式发送信息。由于led的工作速度不到1微秒，因此它的开关速度比人眼所能识别的要快。本文对用于Li-Fi技术的基于直流偏置光OFDM (DCOOFDM)调制的MIMO系统进行了仿真。设计采用MATLAB软件进行仿真，计算系统的接收功率和输出信号。

Performance Analysis of DC-OFDM Modulation Scheme in Li-Fi Communication System

Light Fidelity (Li-Fi) innovation is a wireless communication (WC) system dependent on the utilization of noticeable light between the violet (800 THz) and red (400 THz). Not at all like Wi-Fi which utilizes the radio piece of the electromagnetic range, Li-Fi utilizes the optical range for example Unmistakable light piece of the electromagnetic range. The guideline of Li-Fi depends on sending information by abundancy tweak of the light source in a well-characterized and institutionalized way. LEDs can be turned on and off quicker than the human eyes can identify since the working pace of LEDs is less than 1 microsecond. This paper the simulated of DC biased optical OFDM (DCOOFDM) modulation based MIMO system used for Li-Fi technology. Design is simulated MATLAB software and calculated receiver power and output signal of the system.
