摘要：
In this paper, we propose a family of newly constructed codes, named three-dimensional perfect difference codes (3-D PD codes), and a corresponding system structure for spectral/time/spatial optical code division multiple access (OCDMA). The 3-D PD codes, which are generated from the perfect difference set, can further suppress the phase-induced intensity,noise (PIIN) and possess the multiuser interference (MUI) cancellation property. Compared with the OCDMA systems using modified quadratic congruence codes (MQC codes), maximal-area matrices codes (M-matrices codes), or 2-D PD codes, the proposed system can effectively suppress the PIIN and eliminate MUI. Hence, the proposed system not only has better performance, but also can accommodate more users.
