| Abstract(in English) | The development of Internet technologies such as smartphones and computers has created congestion on mobile networks and Wi-Fi. Optical wireless communication technology is being studied as means to solve line congestion. By using optical wireless communication, which is in a different frequency band from radio waves, it is expected to increase transmission capacity. In MIMO systems, it is necessary to properly separate multiple transmission signals from the received signal. In this study, we apply the maximum likelihood estimation method with high signal separation accuracy to MIMO optical wireless communication systems. The results of a theoretical and experimental comparison between the maximum likelihood estimation and the ZF method which has been studied previously, are presented. |
