New design of spectral amplitude coding in OCDMA with zero cross-correlation
(Elsevier B.V. (Imprint: NORTH-HOLLAND), 2009-07)
A zero cross-correlation (ZCC) code is proposed to reduce the impact of system impairment and multiple access interference (MAI) in spectral amplitude coding optical code division multiple access (SAC-OCDMA) system. ...
Random diagonal codes for spectral amplitude coding optical CDMA systems using fiber Bragg-Grating
(Institute of Electrical and Electronics Engineering (IEEE), 2008-08-26)
In this paper we study the use of a new code called Random Diagonal (RD) code for Spectral Amplitude Coding (SAC) optical Code Division Multiple Access (CDMA) networks, using Fiber Bragg-Grating (FBG), FBG consists of a ...
Improving bit error rate of OCDMA systems using and subtraction technique
(Institute of Electrical and Electronics Engineering (IEEE), 2006)
A new detection scheme, namely AND subtraction technique is proposed and presented in this paper. The theory is being elaborated and experimental results have been done by comparing Double-Weight (DW) code against the ...
Encoder and decoder modules of OCDM system using fiber-bragg grating (FBG) for metro area network
(Institute of Electrical and Electronics Engineering (IEEE), 2008-08-26)
Encoder and decoder modules of OCDM system using Fiber Bragg Grating (FBG) is presented in this paper. In OCDM system, the unique code sequence is formed by using spectral components which are inherently arranged. This is ...
