New Code Structure for Enhanced Double Weight (EDW) Code for Spectral Amplitude Coding OCDMA System

This paper presents a new structure for spectral amplitude coding optical code division multiple access systems based on the enhanced double weight (EDW) code. The new structure is based on mathematical model and step sequences. The reconstruction is carried for higher weighted code to build the code matrix by rules which will make high level weight inspection automatic sequenced and mathematically formed. Some simulation results are shown with comparison on performance.
