Optical Code Division Multiple Access Systems
The optical code division multiple access (optical CDMA) systems is a versatile multiple access technique as compared to time division multiple access (TDMA) and wavelength division multiple access (WDMA). In optical CDMA, the users are assigned unique codes whereas the WDMA and TDMA systems users are assigned different wavelengths or time slots so as to distinguish the data recovered at the re...
متن کاملPerformance Evaluation of One and Two Dimensional Prime Codes for Optical Code Division Multiple Access Systems
Abstract—In this paper, we have analyzed and compared the performance of various coding schemes. The basic ID prime sequence codes are unique in only dimension, i.e. time slots, whereas 2D coding techniques are not unique by their time slots but with their wavelengths also. In this research, we have evaluated and compared the performance of 1D and 2D coding techniques constructed using prime se...
متن کاملPolarized Optical Orthogonal Code for Optical Code Division Multiple Access Systems
In this paper a Polarized Optical Orthogonal Code (Polarized-OOC) is proposed by exploiting the polarization property of the fiber and the chip’s polarization state. The polarized-OOC code is generated using the concept of Mark Position Difference (MPD) set. Polarized-OOC code cardinality is shown to be two times that of the conventional OOC which reflects an increase in the number of supported...
متن کاملReview on Optical Code Division Multiple Access Systems
With the emergence of network driven applications and high speed requirements in communication along with security and large bandwidth, there is a need for a network technique which is capable of providing all the above with a reduced cost. A multiple access technique called Optical Code Division Multiple Access (OCDMA) seems to be fulfilling the above criteria. OCDMA combines the large bandwid...
