Visible light communication using LED is a technique for transmitting digital data using the light of the LED. Recently, high-speed data rate plays an important role. Therefore, many scholars have researched the MIMO-VLC which is able to increase data rate using a lot of LED transmitters. However, it has problems such as light interference and flicker when transmitting different bit. Many researcher have focused on reduce interference. However it is not considered about flicker problem. Flicker is defined unstable brightness. It occurred the tired of human eyes, lowers eyesight and also decreases concentration. In order to solve this flicker problem in MIMO-VLC, we propose the PFM(Parallel Flicker Mitigation) code. PFM code using combinatorial theory can maintain constant brightness the whole bit duration. Therefore, it is possible to assure the brightness by confirm simulation results.
