Optical Single Carrier Frequency Domain Channel Equalizer for Visible Light Communication

Abstract

Optical radio communication systems and its application, visible light communication (VLC), provide very important technical and operational advantages in applications. In this study, it is recommended to use optical single carrier frequency domain channel equalizer (OSC-FDCE) to repair corrupted data of single carrier VLC systems in multipath optical channel environment. Computer simulation studies are performed to test the performance of OSC-FDCE method in 5, 6 and 10 branch optical channel environment over the Bit Error Rate (BER) performance criterion. From the obtained simulation results, it is seen that OSC-FDCE method has better performance than VLC-OFDM-FDE method.
