Study of the OCDMA Transmission Characteristics Using Bidirectional Optical Fiber Link, Based on EDW Code

Abstract

Discussion on free space optics as a link was done by numerous studies by using EDW code. In this paper, we discuss the bidirectional fiber as a connecting media channels. This unit was tested by using the Enhanced Double Weight (EDW) code, which is designated as an outstanding applicant because it had displayed very good performance wherein the total noise is decreased. It is also easy to build and can decrease the required filter numbers at receiver by anew proposed
