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 کاملNovel Codes Family for Modified Spectral-Amplitude-Coding OCDMA Systems and Performance Analysis
—In this paper a novel family of codes for modified spectral-amplitude-coding optical code division multiple access (SAC-OCDMA) is introduced. The proposed codes exist for more number of processing gains comparing to the previously reported codes. In the network using these codes, the number of users can be extended without any essential changes in the previous transmitters. In this study, we p...
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 کاملSpectral efficiency of OCDMA/OCDMA with asymmetric power assignment
In this paper, the sum capacity of the OCDMA/OCDMA (O/O) signature sequence set is investigated when the users of the two orthogonal sets are allowed to have a different average-input-energy constraint and with perfect synchronization of the users. It is found that the sum capacity is dependent on the load and the respective SNR only, but independent of the choice of the orthogonal sets. For a ...
