Polarized 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 کاملOptical 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 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...
متن کاملQuasi-orthogonal sequences for code-division multiple-access systems
In this paper, the notion of quasi-orthogonal sequence (QOS) as a means of increasing the number of channels in synchronous code-division multiple-access (CDMA) systems that employ Walsh sequences for spreading information signals and separating channels is introduced. It is shown that a QOS sequence may be regarded as a class of bent (almost bent) functions possessing, in addition, a certain w...
متن کاملPerformance Analysis of Multiple User Optical Code Division Multiple Access
In this paper, we discuss and analyze an optical code division multiple access for multiple user system. Media access control implementation has been considered. For fulfilling the huge need of bandwidth services, technology tends to move to optical networks and three major optical systems come into existence. Code division of the optical network is most used and real concept interacted with us...
