Summary:
In this paper, we propose an optical ZCZ-CDMA system using a two-dimensional(2D) optical zero-correlation zone (ZCZ) sequence set that is orthogonal in a 2D zone around shift 0. In order to show the effectiveness of the proposed method, we evaluated the BER characteristics of the optical codedivision multiple access(OCDMA) system using a 2D Hadamard sequence or a 2D ZCZ sequence set by computer simulation. As a result, it has been confirmed that the method using the 2D ZCZ sequence set has better BER characteristics than the 2D Hadamard sequences and that the BER is improved by increasing the zero-correlation zone.
