Construction of a new code for spectral amplitude coding in optical code-division multiple-access systems
(Society of Photo-Optical Instrumentation Engineers (SPIE), 2007-07)An enhanced code structure for spectral amplitude coding in optical code division multiple access systems based on double weight (DW) code families is proposed. Enhanced double weight (EDW) codes possess ideal cross-correlation ... -
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 ... -
New code structure for spectral amplitude coding in OCDMA system
(The Institute of Electronics, Information and Communication Engineers, 2007)A new code structure for spectral amplitude coding optical code division multiple access system, based on Double Weight (DW) code families is proposed. The DW code has a, fixed weight of two. Modified Double Weight (MDW) ... -

(The institute of Electronics, Information and Communication Engineers (IEICE), 2008-10)A new code structure for spectral amplitude coding in optical code division multiple access (OCDMA) systems called Smart Direct Detection (SDD) code is proposed. SDD code is constructed using code segment and data segment. ... -
A new two-code keying scheme for SAC-OCDMA systems enabling bipolar encoding
(Taylor & Francis, 2014-03)In this paper, we propose a new two-code keying scheme for enabling bipolar encoding in a high-rate spectral-amplitude coding optical code-division multiple-access (SAC-OCDMA) system. The mathematical formulations are ... -
Reducing BER of spectral-amplitude coding optical code-division multiple-access systems by single photodiode
(European Optical Society, 2013)In this paper, we present a single photodiode detection (SPD) technique for spectral-amplitude coding optical code-division multiple-access (SAC-OCDMA) systems. The proposed technique eliminates both phase-induced intensity ... -
