Analysis of different OCDMA techniques: A Review
نویسنده
چکیده
The use of optical fiber which offers large bandwidth in the telecommunication sector has shown a lot of developments in the last decade mainly in television cables and cell phone cables. But these are not fully efficient and to do this, the fiber should allow multiple access which means allowing various users to send and receive data in the fiber at the same time. There are three main schemes of multiple access namely, Time Division Multiple Access (TDMA), Wavelength-Division Multiplexing (WDM) and Code Division Multiple Access (CDMA). In this paper, different types of optical networks using CDMA has been reviewed. CDMA is one of best multiple access scheme that allows a great flexibility in multiple accesses. It provides secure and asynchronous transmission. KeywordsCDMA, optical fiber, multiple access. __________________________________________________*****_________________________________________________
