New Approach of Flexible Cross Correlation (FCC) Algorithm for Noise Alleviation on OCDMA Systems
نویسنده
چکیده
The flexible cross correlation (FCC) code algorithm for optical code division multiple access (OCDMA) systems has been developed. The FCC approach has advantages, such as flexible cross-correlation property at any given number of users and weights, as well as effectively suppressed the impact of phase-induced intensity noise (PIIN) and multiple-access interference (MAI) cancellation property. The results revealed that the FCC code can accommodate 150 users, where FCC code offers 66%, 172%, 650% and 900% improvement as a contrast to 90, 55, 20 and 15 numbers of users for Dynamic Cyclic Shift (DCS), Modified Double Weight (MDW), Modified Frequency Hopping (MFH) and Hadamard codes respectively, for a permissible bit error rate (BER) of 10. Keywords—FCC Code; Correlation Properties; MAI; OCDMA Systems.
