Improved BER based on intensity noise alleviation using developed detection technique for incoherent SAC-OCDMA systems
(Taylor and Francis Group, LLC., 2012-06)The major drawback of incoherent spectral-amplitude coding optical code-division multiple-access (SAC-OCDMA) systems is their inherent intensity noise originating due to the incoherency of the broadband light sources. In ... -
Improved probability density function using modified-AND detection technique for incoherent SAC-OCDMA systems
(Institute of Electrical and Electronics Engineers (IEEE), 2012-07-03)The rapid progress in video-based Internet applications is increasing the demand for efficient optical communication systems. In this paper, developed detection technique for incoherent spectral-amplitude coding optical ... -
Intensity noise mitigation in SAC OCDMA systems using a divided spectrum balanced detection scheme
(Institute of Electrical and Electronics Engineers (IEEE), 2013-09)We propose the use of a divided spectrum balanced detection (DSBD) to reduce the intensity noise in spectral amplitude coding (SAC) OCDMA systems. Simulation results show several order of magnitude improvements in bit error ... -
Spectral efficiency of unipolar SAC-OCDMA system considering noise effects
(Institute of Electrical and Electronics Engineers (IEEE), 2011-09-25)In this paper, we evaluate the spectral efficiency of unipolar spectral-amplitude coding optical code-division multiple access (SAC-OCDMA) system operating with incoherent sources in the present of intensity, shot, and ...
