A new direct detection technique is proposed for optical code multiple accesses using Double Weight code. In optical system the detection process affect design transmitter and receiver. The Multiple Access Interference ...

This paper investigates the performance of enhanced double weight (EDW) code for spectral-amplitude-coding OCDMA (SAC-OCDMA) system using a newly proposed spectral direct detection (SDD) technique. EDW is the enhanced ...

What we believe to be a new code structure to reduce the multiple access interference in a spectral amplitude coding optical code-division multiple access system based on double-weight code families is proposed. Enhanced ...
