An Offline Space Division Multiplexing Based Elastic Optical Network Model with Switching and Modulation Format Adaptation for Flexible Spectrum and Spatial Assignment
Abstract: Abstract: The Space Division Multiplexing (SDM) based Elastic Optical Networks (EONs) (SDM-bEONs) is the proposed solution to both, the required upgradation of the network’s capacity constrained by the non-linear Shannon’s limit and the provisioning needed for the future diverse Internet traffic’s required capacity. With SDM providing ‘space’ as an additional freedom degree, the assignment of resource (i.e., spectrum and space) in the SDM-b-EONs translates into the Routing, Modulation Format, Space, …

Analysis of M-ary Signaling for Weak Turbulence Regime in FSO Communication System
Abstract: Abstract: The need for high data rate LOS communication is accomplished using the Free Space Optical communication. Being a very cost-effective approach, it contributes to the easy set-up and deployment of point to point terrestrial link. It transmits the light signal in free space channel (air, vacuum etc.) using LASERs or LEDs and received via photodetector. In this paper, the channel is modelled using Lognormal turbulence model. This channel model …

Effect of ETL layer thickness on perovskite (CH3NH3PbI3) solar cell
Abstract: Abstract: Thickness of ETL (Electron transport layer) shows important role in term of stability and efficiency of perovskite solar cells. In this paper the numerical simulation and extensive modeling have been performed on perovskite solar cell using perovskite material such as methyl ammonium lead Iodide (MAPbI3, MA=CH3NH3) with the help of SCAPS tool. The electrical properties of the MAPbI3 material used as active layer, have been calculated for different parameter …

Modeling of Photovoltaic Module with MATLAB/Simulink
Abstract: Abstract The generation of electrical energy from sunlight is achieved with an interface called photovoltaic (PV) module. The PV module plays a vital role for extracting electrical energy from sunlight, thus its accuracy is most important parameter for consideration while developing mathematical model of PV module. For higher accuracy the single diode model with series and parallel resistors combination is used. For simulating this device in MATLAB/Simulink we need weather …

Performance Comparison of Hadamard Code and MultiDiagonal Code in SAC-OCDMA system
Abstract: Abstract: The objective of this study is performance Comparison of two different coding techniques in spectral-amplitude coding OCDMA (SAC-OCDMA) Here two such codes. Hadamard code and multi-diagonal code are simulated in OCDMA codes have been compared in terms of the BER, length and data rate First, we simulate the OCDMA using Hadamard code. And analyze the performance of OCDMA system. Again, simulate the OCDMA using MD code. Then compare both …
