In this article, a subcarrier-multiplexed Optical CDMA system utilizing the direct and AND subtraction method in receiver's detection is explored. The OCDMA part exploits the Recursive Combinatorial (RC) code for its algorithm. The two different designs are then simulated and the performances are compared. Results indicate that the hybrid SCM/OCDMA system using direct detection technique could transmit...
In this paper, different detection technique is presented through bit rate 1Gbps. Advanced modulation technique is used for enhancing the performance of optical access network. Differential phase shift keying (DPSK) has significant attention for the researcher during last two decades. Optisystem version 12 has been employ for investigate the transmission capability of the hybrid system. The comparison...
This paper presents the numerical analysis of 2Dimensional (2-D) FCC-MDW of the Optical Code Division Multiple Access (OCDMA) based on variations of transmission bit rate. This 2-D OCDMA code is a combination of 1-D Flexible Cross Correlation (FCC) and 1-D Modified Double Weight (MDW). The performance of 2-D FCC-MDW is evaluated at different bit rate; 622Mbps, 1Gbs and 2.5Gbps and can be demonstrated...
