Unimodal and Multimodal Biometric Sensing Systems: A Review

ABSTRACT

Biometric systems are used for the verification and identification of individuals using their physiological or behavioral features. These features can be categorized into unimodal and multimodal systems, in which the former have several deficiencies that Continue reading

A Key Space Enhanced Chaotic Encryption Scheme for Physical Layer Security in OFDM-PON

ABSTRACT

In this paper, we propose a key space enhanced chaos-based encryption scheme with no requirement of redundant sideband information in an orthogonal frequency division multiplexing passive optical network (OFDM-PON). For the first time, a simple Continue reading

Analysis of Fix‐point Aspects for Wireless Infrastructure Systems

ABSTRACT

A large amount of today’s telecommunication consists of mobile and short distance wireless applications, where the effect of the channel is unknown and changing over time, and thus needs to be described statistically. Therefore the received signal Continue reading

Generating an Isolated Word Recognition System Using Matlab

ABSTRACT

MATLAB’s straight forward programming interface makes it an ideal tool for speech analysis. In this work, experience was gained in general MATLAB programming. A basic speaker recognition algorithm has been written to Continue reading

Using Matlab Tools for Simulation of the Optical Transmission Medium

ABSTRACT

The paper presents a design and simulation of the optical path which include linear and nonlinear effects using the MATLAB simulation tools. The program includes a calculation part of nonlinear effects and a simulation part where the signal is examined Continue reading

Numerical Analysis of Orbital Angular Momentum based Next Generation Optical SDM Communications System

ABSTRACT

In this paper, we make a theoretical and numerical analysis of a transmission chain based on an Orbital Angular Momentum (OAM) technique in the case of ideal channel. In order to generate an OAM beam, we define a theoretical OAM encoder (vortex generator) similar Continue reading

The Laser Satellites Communications and Laser Noises

ABSTRACT

The gain of advanced optical communication systems is reduced by the noise of optical source. Coherent optical communication systems are in particular very sensitive to the noise transmitter and local laser. Optical space communications is on the verge Continue reading
