Hilal A. Fadhil,Angela Amphawan,Hasrul A.B. Shamsuddin,Thanaa Hussein Abd,Hamza M. R. Al-Khafaji,Syed Alwee Aljunid,Nasim Ahmed +6 more
TL;DR: From the result analysis, FSO wavelength with 1550 nm produces less effect in atmospheric attenuation, and it is recommended to develop a system of quality-free space optics for a high data rate transmission.
Journal ArticleDOI
Development of a new code family based on SAC-OCDMA system with large cardinality for OCDMA network
TL;DR: Simulation results show this new Multi-Diagonal code for Spectral Amplitude – Coding Optical Code Division Multiple Access to provide a much better performance compared to Modified Quadratic Congruence (MQC) code and Random Diagonal (RD) code.
Journal ArticleDOI
Performance of random diagonal code for OCDMA systems using new spectral direct detection technique
TL;DR: It is shown that the proposed new spectral direct detection technique utilizing RD code considerably improves the performance compared with the conventional SAC complementary subtraction technique.
Journal ArticleDOI
Development of Multi-Service (MS) for SAC-OCDMA systems
TL;DR: Results show that by choosing code weight of 4 and optimizing number of users per sequence, the MS code supports up to 82 users, each operating at a bit-rate of 622 Mbps with reference to the Bit Error Rate (BER) of 10−9.
Journal ArticleDOI
A new two dimensional spectral/spatial multi-diagonal code for noncoherent optical code division multiple access (OCDMA) systems
TL;DR: The analytical and the simulation results reveal that the proposed 2D-MD code outperforms the other codes and a large number of simultaneous users can be accommodated at low BER and high data rate.
