Abstract: In this dissertation, Li-Fi communication using Complementary Metal-Oxide Semiconductor (CMOS) image sensor is demonstrated. Smartphone camera is used as receiver to capture the information transmitted by LED light and captured image is processed . in order to process the CMOS sensor image, a MATLAB Algorithm/program is developed. LED is used as transmitter which sends the Li-Fi based signal . Nowadays, the smartphones equipped with built-in CMOS camera and this camera is used as receiver which captures the information from LED light in the form of image by using the shutter speed and ISO properties. The captured image is processed using the image processing algorithm. I have developed the image processing algorithm using MATLAB software. The image processing algorithm developed will take the captured image as input and process it. The algorithm developed extracts the information from the image captured using the smartphone CMOS camera from a LED light which transferring the information in the form of 1’s and 0’s . In this dissertation, the image processing algorithm developed to recover the information transmitted will be discussed in detail.
