Optical-CDMA Systems Research Paper by Nicky

The paper explains that code division multiple access (CDMA) is a type of communication using multiplexing that help in radio transmission and wireless networks. The paper also explains optical code division multiple access (OCDMA) as a "next generation CDMA" technology which uses fiber-optic technology. The paper describes the method by which optical CDMA systems work and explains the steps necessary to achieve multiplexing. The paper then shows how a CDMA communication system based on optical codes is different from radio and wireless systems and possesses unique attributes and advantages. The paper looks at the various codes that have been designed for use in OCDMA devices and discusses the two categories of OCDMA devices. The paper explores the aspects of OCDMA on which research efforts are being organized and illustrates the technological barriers to the general acceptance of OCDMA devices. However, the paper concludes that OCDMA possesses a number of advantages which make it a promising candidate for the multiple-access networks of the future.
