New code structure for spectral amplitude coding in OCDMA system
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) code possesses ideal cross-correlation properties and the weight can be any even number, which is grater than two. The MDW code possesses ideal cross-correlation properties and...
متن کاملSpectral Amplitude Coding Ocdma Systems Using Enhanced Double Weight Code
A new code structure for spectral amplitude coding optical code division multiple access systems based on double weight (DW) code families is proposed. The DW has a fixed weight of two. Enhanced double-weight (EDW) code is another variation of a DW code family that can has a variable weight greater than one. The EDW code possesses ideal cross-correlation properties and exists for every natural ...
متن کاملPerformance Analysis of Zero Cross-Correlation Code in Spectral Amplitude Coding-OCDMA
Optical Code Division Multiple Access (OCDMA) has bright future in communication because of its faster speed, efficiency, security and unlimited bandwidth. To reduce Multiple Access Interface (MAI) and Phase Induced Intensity Noise (PIIN) noises there are many codes in Spectral Amplitude Coding-Optical Code Division Multiple Access (SAC-OCDMA) with codes best property i.e., minimum cross-correl...
متن کاملDifferential Service in a Bidirectional Radio-over-Fiber System over a Spectral-Amplitude-Coding OCDMA Network
A new scheme of radio-over-fiber (RoF) network based on spectral-amplitude-coding (SAC) optical code division multiple access (OCDMA) is herein proposed. Differential service is provided by a power control scheme that classifies users into several classes and assigns each of them with a specific power level. Additionally, the wavelength reuse technique is adapted to support bidirectional transm...
متن کاملDesign and Demonstration of a Novel Spectral Amplitude Coding OCDMA Code for Suppression Phase Intensity Induced Noise
A new code for spectral-amplitude coding optical code-division multiple-access system is proposed called Random diagonal (RD) code. This code is constructed using code segment and data segment. One of the important properties of this code is that the cross correlation at data segment is always zero, which means that Phase Intensity Induced oise (PII ) is reduced. For the performance analysis, t...
