Abstract: A novel scheme for high-speed high-performance multimedia transmission using visible light communication is presented. Initially, the multimedia image is converted to digital data. This digital data is divided into three sub-streams and each sub-stream is then transmitted via three parallel channels. Prior to transmission, each sub-stream data is modulated using on-off keying (OOK) modulation. Three parallel channels corresponding to each colour (red, green and blue) of a RGB LED are utilised for transmission, thus giving a total of nine channels. Colour filters (CFs) and selection combining (SC) are also utilised for performance improvement and high speed transmission. Simulations are performed to evaluate the effectiveness of the proposed scheme. Results show that the proposed scheme is efficient in terms of bit-error-rate (BER) performance and data rate. Thus, it can effectively be used for high speed multimedia transmission.
