A CONSTRUCTION METHOD OF OPTICAL ORTHOGONAL CODE BASED ON DIFFERENCE SET

摘要：

Optical orthogonal codes (OOCs) have application in OCDMA system because of their good correlation properties. In this paper, two correlation-detection methods, difference method and distance method, were studied. Calculate amount of these correlation-detection methods was analyzed. Constraint condition of optimal optical orthogonal codes was discussed. Besides, a construction method of optimal (n,w,1) optical orthogonal code was presented based on difference set. Optimal (n,w,1) optical orthogonal code which has 2 code words each set was constructed by this construction method. Codewords relativity simulation proved the validity of the method. This construction method has practicability because of codewords good correlation properties and large capacity.
