The Orthogonal variable spreading factor (OVSF) codes were first introduced for 3G standards. The OVSF are channelization codes are widely used for preserving the orthogonality between physical channels in a communication ...
This paper presents FPGA based implementation of the theory which replaces a general Sine and cosine function by set of orthogonal functions i.e. Walsh function. The paper further compares Parameterized `Serial In Serial ...
This paper reports a comparative investigation of different pulse shapes for optical transmission among Gaussian, super-Gaussian and soliton pulses under the effect of dispersion, fiber loss and initial chirp. MATLAB is ...
This paper presents a simulative analysis of 40Gb/s Return-to-Zero Differential Quadrature Phase Shift Keying (RZ-DQPSK) scheme under Self Phase Modulation (SPM) and Amplified Spontaneous Emission (ASE) over three commonly ...
This paper attempts to present the design approach for development of simulation models to study and analyze the transmission of 10 Gbps DQPSK signal over a single channel Peer to Peer link using Matlab Simulink. The ...
The Wavelength routed optical network employs well preconfigured optical lightpaths to carry the traffic of users to communicate in the internet at an increasingly huge data rate. The optical network requires lightpaths ...
In this paper, we consider the Routing and Wavelength Assignment problem in WDM optical networks. We consider the dynamic traffic and assume that in each optical fiber the number of wavelengths has fixed. In this paper, ...
The model for current and manufacture of a moderately doped nanoscale FinFETs with parabolic cross section is proposed. The model of trapezoid FinFETs is extended to parabolic FinFETs, furthermore diminishing corner effects. ...
The weak strength of GPS signal makes it very vulnerable to jamming. This calls for appropriate modeling and implementation of GPS signal source and jammers that are used to jam GPS signal. The present work describes a ...
This paper presents the dynamic survivable lightpath protection problem using probabilistic Intelligent Water Drops algorithm in wavelength-routed WDM networks. Primary lightpath and backup lightpath computation performed ...
Vehicular Ad Hoc Networks requires an efficient routing strategy applicable to any random vehicular movement to fix network layer parameters to enhance the packet delivery ratio, data throughput and packet delivery latency. ...
Using a fairly rigorous approach, a general characteristic equation for a doubly clad step-index fibre has been derived under the assumption that the refractive-index difference between the inner and outer cladding is ...
A general characteristic equation is derived for a four-layer metal-clad graded-index slab waveguide with a guiding layer having a semi-parabolic refractive index profile. The attenuation parameter for the lowest-order TE ...
Relative field intensity distributions in three differenttypes of structures, i.e. Step index Slab Waveguide(SSW), Semi-parabolic index Slab Waveguide (SPSW)and Parabolic index Slab Waveguide ...
Diffusion techniques have provided as alternative to thin-films technology for the fabrication of planar optical waveguides in CdS, ZnSe, LiNbO3, and LiTaO3 etc.
Since the first low-loss fiber in 1970, fiber-optics emerged from being a laboratory curiosity to constitution a significant portion of the communications and sensors business
Call connection probability in an all optical network (AON) using wavelength division multiplexing (WDM) depends on the number of WDM wavelengths available in a link and on the network capability for wavelength conversion ...
We aim to implement a new deterministic wavelength conversion algorithm in local area networks (LANs). The network has been studied from a layered approach, and we describe how it can be interpreted as both a trunk network ...
