Ltd.,PERFORMANCE ANALYSIS OF 2-D OPTICAL CODES WITH CROSSCORRELATION VALUE OF ONE AND TWO IN OPTICAL CDMA SYSTEMANKIT AGARWAL, NITIN AGARWAL AND CHAGANTI RAJASEKHARElectronics & Communication Engineering Department, Jaypee Institute of Information Technology,Noida, India 201307Email Id:- ankitsagarwal@gmail.com, nitin.ag3@gmail.com,rajasekhar.chaganti@gmail.comABSTRACTOptical Code-Division Multiple Access (OCDMA) is an optical processing system which allowsmultiple users to share the same bandwidth simultaneously without interfering with each other usingunique optical codes. In this paper, we analyze the performance of Two Dimensional (2-D) optical codesby varying the cross correlation value (one and two) for OCDMA system. The OCDMA system ascompared to prime codes (one-dimensional codes) supports large value of cardinality (i.e. to increasesthe number of subscribers) and heavier code weight for better code performance and for more number ofsimultaneous users.KEYWORDS : OCDMA,MWOOC, CROSS CORRELATIONINTRODUCTIONOCDMA has an advantage of combining the large bandwidth of optic-fiber media and the flexibilityof CDMA techniques. OCDMA received renewed attention because of the advancement of wavelengthspreading and time hopping technology in optical codes. The multiple wavelength op
