Multiple Access Techniques for Fiber-Optic Networks

“…The last hybrid multiple access scheme that will be mentioned here combines three of the four basic access techniques, namely WDMA/SCMA/CDMA [188]. This is illus -FIG.…”

Optical Fiber Code Division Multiple Access Networks: A Review

“…This is a very promising property of SAWs, although it has to be recognized that such devices operate to frequencies up to 1 GHz maximum. Theoretical papers describing such a system operating under different scenarios, such as the use of multimode fibers for short distance LAN applications, can also be found in the literature [118,119].…”

Enhancement of performance of a hybrid SAC-OCDMA system using dynamic cyclic shift code

“…With the present level of technology, however, applications of the LAN are mainly limited by high costs of their optical components [1]. Optical code division multiple access (OCDMA) has always been of concern because of its inherent capability to support asynchronous-access networks, dynamic bandwidth assignment, and ability to support multimedia services [2,3].…”

“…In addition, to study performance of the system with the DCS code, we will take into account the effect of different noises such as the PIIN, the shot and thermal noises). A technology of subcarrier multiplexing (SCM) has already demonstrated its great potential to become a convenient and efficient technique for transmission of analogue or digital information [1]. Therefore hybrid SCM-OCDMA networks that employ the two efficient techniques, SCM and OCDMA, should be of a particular interest.…”
