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

Abstract

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.
