Semi-randomly constructed optical orthogonal codes

Optical orthogonal code (OOC) sequences are assigned to optical code-division multiple-access (OCDMA) network users, who are able to transmit data asynchronously. In this work, we propose a semi-random OOC design technique based on extended sets, where the input parameters are the sequence weight, number of sequences (i.e., users), and a target sequence length. The design method under consideration is able to converge to the desired short OOC lengths given the number of iterations during the execution of the algorithm is sufficiently large.
