| Abstract(in English) | In this paper, we propose the new two-dimensional (2D) optical code-division multiple access (OCDMA) with pulse position modulation (PPM) system and the new generation method of optical zero-correlation zone (ZCZ) sequences suitable for the proposed system. The proposed system prevents illumination degradation by assigning the 2D optical sequence to all slots by cyclic shifting. The proposed 2D optical sequences have ZCZ at multiple positions and equal intervals of the output of the 2D correlation function. By applying this sequence to the proposed system, the system can suppress interferences caused by neighboring light-emitting elements. In addition, the bit-error rate (BER) characteristics can be expected to improve. |
