Abstract: Based on the Synchronous Modified Prime Codes(SMPC),a two-dimensional Synchronous Modified Prime Codes(2D-SMPC) is constructed by assigning each different wavelength for each different seed.The correlation performance of 2D-SMPC is analyzed and the choice principle of the address codewords is obtained.Multiple Address Interface(MAI) and the system capacity are studied by Optisystem simulation.Compared with one-dimension SMPC,the performance improvement in Synchronous Optical Code Division Multiple Access(S-OCDMA) system is proven.

Key words: Synchronous Optical Code Division Multiple Access(S-OCDMA), 2D-synchronous modified prime codes, system capacity, multi-address interface

摘要: 在同步修正素数码(SMPC)基础上,通过给每个不同的种子分配一个不同的波长片,构造了二维正交地址码(2D-SMPC);分析了码字的相关特性,确定了地址码选取原则;通过Optisystem仿真,研究了该码的多址干扰(MAI)和系统容量等性能。与一维SMPC码性能相比较,验证了其用于S-OCDMA系统时的性能改善。
