Since there is nothing in the universe that moves more quickly than light, visible light communication (VLC) opens the door to extremely fastcommunication by using light to convey data. VLC uses light-emitting diodes (LEDs) as a source to provide white light and carry information through free space in addition to lighting. Achieving data in GB/s with long-distance transmission by considering background noises is critical in VLC. This research work focuses on the design and analysis of Gigabit Class VLC-based MC-MB with Quadrature Amplitude Modulation (QAM) and Reed Solomon (RS) coding with background noises for Direct Line of Sight (DLOS), Non-Direct Line of Sight (NDLOS), and Non-Line of Sight (NLOS) VLC channel models. MC is demonstrated using RGBY-LEDs to get high data rates. MB to add redundancy and reliability. RS is used to reduce errors due to background noises and the free space channel. QAM is used for symbol generation because of its higher spectral efficiency, efficient bandwidth, and robustness to noise. Green, ultraviolet, white, flashlight, spectrum, red, blue, and yellow background noises are added to the channel. To analyze the proposed model, an overall communication system is designed and simulated. Using the designed system, simulation results showed that MC-MB ( \(4{\times }4\) ) DLOS is 23% at \(45^{\circ }\) field of view (FOV), 16% at \(60^{\circ }\) transmitter half-angle (THA), and 24% at \(1\,\mbox{cm}^2\) photodetector (PD) area better than NDLOS in terms of received optical power, respectively. Further, NLOS has lower performance than DLOS and NDLOS.
