A Technique for Orthogonal Frequency Division Multiplexing
Frequency Offset Correction

Abstract:
The Orthogonal Frequency Division Multiplexing (OFDM) is a Multi Carrier Modulation technique employing Frequency Division Multiplexing of orthogonal subcarriers. It is also sometimes called as discrete multitone modulation (DMT). It is better than CDMA in high bit rate and Broadband Communications .It is a multi carrier technique, which is very sensitive to Frequency Offset between transmitter and receiver. Th ....etc

This Image Steganography in frequency domain using DFT project was developed in Matlab tool for final year ECE & EE students, By using Steganography and DFT concept we will hide secrete image/message in the cover image. For encryption of the data and images we will use data encoding algorithm.In today's communication world, data sharing and transfer is increasing exponentially. The threat of an attacker accessing secret information has been an ever existing concern for the data communication experts. Cryptography and steganography are the mos ....etc

BGM-109 Tomahawk missile aerodynamic coefficients

The Tomahawk (US / t m h k/ or UK / t m h k/) is a long-range, all-weather, subsonic cruise missile named after the Native American axe. Introduced by McDonnell Douglas in the 1970s, it was initially designed as a medium to long-range, low-altitude missile that could be launched from a surface platform. It has been improved several times, and due to corporate divestitures and acquisitions, is now made by Raytheon. Some Tomahawks were also manufactured by General Dynamics (now Boeing Def ....etc

Abstract
The problem of estimating the kth frequency moment Fk over a data stream by looking at the items exactly once as they arrive was posed in . A succession of algorithms have been proposed for this problem . Recently, Indyk and Woodru have presented the rst algorithm for estimating Fk, for k > 2, using space O (n1 2=k), matching the space lower bound (up to poly-logarithmic factors) for this problem (n is the number of distinct items occurring in the stream.) In this paper, we presen ....etc

frequency warping matlab code

Introduction

WarpTB is a MATLAB toolbox for frequency-warped signal processing. Practically any signal processing algorithm can be warped by replacing all the unit delay elements by first order allpass blocks. Frequency-warping changes the frequency resolution of the system. Using a suitable value for a warping coefficient LAMBDA, the frequency-resolution of the system approximates closely the frequency resolution of human auditory system. This makes frequency-warped signal processing techniques beneficial in man ....etc

SPEAKER IDENTIFICATION USING MEL FREQUENCY CEPSTRAL COEFFICIENTS


1. INTRODUCTION
Speech is one of the natural forms of
communication. Recent development has made it
possible to use this in the security system. In
speaker identification, the task is to use a speech
sample to select the identity of the person that
produced the speech from among a population of
speakers. In speaker verification, the task is to use a
speech sample to test whether a person who claims
to have pr ....etc
