Summary:
In optical parallel communications using RGB LEDs, the different attenuation rates of each colors cause the partial erasure channel, which makes the performance of communications down seriously. In this paper, a novel parallel optical Turbo-code communication system using RGB LEDs is proposed and investigated. It is assumed to be effective to solve the partial erasure channel transfer problem by re-arranging the Turbo-code parity-bit streams. Binary Pulse Position Modulation (BPPM) is used as the modulation technique. Moreover, for showing the effectiveness of the proposed system, the bit error rate (BER) performance of the proposed system is analyzed by computer simulation in Addict White Gaussian Noise (AWGN) channel and Optical Wireless Channel (OWC) taking background noise and scintillation in account, respectively.
