The intent of this paper is to study the performance of spectral-amplitude coding optical code-division multiple-access (OCDMA) systems using Single Photodiode Detection (SPD) under various optical parameters. In our work, we utilized Modified Double weight (MDW) code as one of the OCDMA applications which called “triple-play” services (audio, video, and data) with different quality-of-service (QoS)...
This paper presented a code with non-zero in-phase cross- correlation Spectral Amplitude Coding Optical Code Division Multiple Access (OCDMA) system. The proposed code called Modified Non Zero Cross Correlation (MNZCC) code. The MNZCC code can be constructed easily for any given number of users, weights and cross correlation (λmax) using tridiagonal matrix properties. MNZCC code will be demonstrated...
This paper presented a new class of code called Modified Non-Zero Cross Correlation (MNZCC) Code for Spectral-Amplitude Coding Optical Code Division Multiple Access. The MNZCC code can be constructed easily for any given number of users, weights and cross correlation (λmax) with tridiagonal matrix properties. We find that the performance of MNZCC code is better than OCDMA codes such as MDW and MFH...
In this paper we present a novel code family for SAC-OCDMA system. The new code technique is called Dynamic Cyclic Shift (DCS) code. Which more flexible in selection the code length with variable cross correlation. Furthermore, incase of increasing the number of users there is no need to increase the weight value. In addition the code construction is very simple and easy in compare with the former...
