Performance Comparison of Various Coding & Detection Schemes in OCDMA System

Jeffrey Simon V | Dhanya S [5]

Abstract: In this paper we evaluate efficiency of a hybrid optical CDMA system on various coding & detection scheme. OCDMA system based on sub carrier multiplexed (SCM) & spectral amplitude coding (SAC) is compared using different coding techniques such as Hadamard codes, Double Weighted Codes (DWC) and Enhanced Double Weighted Codes (EDWC) with different detection techniques including complementary, NAND, AND, and XOR. The hybrid system that uses SCM and SAC which improves the data rate in channel as well as mitigates the problem of multiple access interference to a large extend. Upon comparison of different coding schemes like Hadamard codes, DWC & EDWC, EDWC can support maximum users with high SNR and good quality of service for a considerable range of fiber length. Evaluating different detection schemes, AND and XOR detection are equally efficient. So the proposed scheme focus on a SAC-SCM OCDMA system using EDWC with the help of AND & XOR detection technique which improves the performance and efficiency of optical CDMA system which can essentially enhance future requirements.
