Performance Analysis of Hybrid OCDMA/WDM System Complementary Subtraction Detection Technique

Aymen Abdalmunam Hameed

We proposed a hybrid optical code division multiple access (OCDMA) over wavelength division multiplexing (WDM) system is proposed for supporting large numbers of subscriber for fiber to-the-home (FTTH) network. The system combines two different techniques, namely OCDMA and WDM in order to support many subscribers simultaneously. In this study, the hybrid OCDMA/WDM system for FTTH access networking using complementary detection technique and To analyze the performance of the simulated system. the modified double weight (MDW) code is used as signature address in designing the system because this code can accommodate more Number of simultaneous active users under standard acceptable bit-error-rate (e.g. ≤ 10-9). The complementary subtraction detection technique is used to detect the signal.. The MDW code is better than other codes for improving the system performance by reducing the multiuser interference in a significant amount. We have done the result of this paper by using a simulating of matlab. We ascertained by simulation experiments that the proposed system provides high impact performance and enhance the network capacity. The proposed hybrid system would then be a prospective candidate for the future FTTH access network. In this study I will make a comparison between several codes to improve that the proposed MDW is better than others.
