Optimal CDMA: Fundamentals, developments, and applications

Starting from the early 1980s, there have been steady developments in the coding schemes and enabling technologies in optical code division multiple access (O-CDMA). With the advance in technology and recent suport of the U.S. Defense Advanced Research Projects Agency (DARPA), the progress in O-CDMA has been tremendous since four years ago. O-CDMA systems are now closer to be deployable than ever before. In this tutorial, we will first examine various coding schemes and enabling technologies in this area. Then, the recent developments of O-CDMA will be presented. Finally, we will investigate the potential applications and issues of O-CDMA.
