Transmission Performance of Optical Code Division Multiple Access Network Based on Spectral Amplitude Coding
Optical code division multiple access (OCDMA) technique is required to meet the increased demand for high speed, large capacity communications in optical networks. In this paper, the transmission performance of a spectral amplitude coding (SAC)-OCDMA network is investigated when a conventional single mode fiber (SMF) is used as the transmission link. The results can be used as guidelines to ass...
متن کاملInvestigation of in-band transmission of both spectral amplitude coding/optical code division multiple-access and wavelength division multiplexing signals
P. Susthitha Menon Universiti Kebangsaan Malaysia Institute of Microengineering and Nanoelectronics 43600 UKM Bangi, Selangor, Malaysia Abstract. The transmission of both optical code division multiple-access (OCDMA) and wavelength division multiplexing (WDM) users on the same band is investigated. Code pulses of spectral amplitude coding (SAC)/optical code division multiple-access (CDMA) are o...
متن کاملAlleviation Noise Effect Using Flexible Cross Correlation Code in Spectral Amplitude Coding Optical Code Division Multiple Access Systems
-A new code for Spectral Amplitude Coding Optical Code Division Multiple Access (SAC-OCDMA) is proposed and is called Flexible Cross-correlation (FCC) code. The FCC code possesses various advantages; including easy code construction using Tridiagonal matrix compared to other SAC-OCDMA codes such as MDW, MQC and MFH, shorter code length and the important properties of this code is the flexible c...
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...
متن کاملCDMA(Code Division Multiplexing Access)
Multiple users can be served by the same bandwidth in wireless CDMA systems of spread spectrum. The use can used the bandwidth and different codes at the same time and any signal showed by one of the user is seen as interference. This interference is detected to the base station in the process of extracting data used by a specific signal utilized by a user. Users who are closer to the BS are th...
