Summary:
In the illumination visible-light communications, the realization of the communication function and of the positioning function is required while maintaining the lighting function. As the system that satisfies all of these functions, The Variable N-CSK (VN-CSK) system using Modified Prime Sequence Codes (MPSC) has been proposed. In this conventional system, RGB parallel transmission has not been done yet. To improve transmission effiency and positioning accuracy, we condider RGB parallel transmission scheme. In order to achieve RGB parallel transmission, we have to cope with the color spectrum interference and the co-channel interference. We proposed the paralell RGB LEDs transmisson for VN-CSK with MPSC and Modified Pseudo Orthogonal M-sequence (MPOM). We evaluated bit error rate and indicated that the proposed system is suitable for RGB parallel transmission.
