Abstract

This paper proposes a new equalization of indoor visible light communication based on mobile localization. Compared with zero-forcing equalization which has a large noise gain occurring at the deep fading points. Minimum mean square error equalization is more suitable for multi-channel and it performs well in equalization. By combining the mobile positioning technology and the single-carrier frequency domain minimum mean squared error equalization, the proposed method of equalization can simply counteract inter-symbol interference without inserting training sequences.
