A NOVEL METHOD OF COMPRESSING SPEECH WITH HIGHER BANDWIDTH EFFICIENCY

INTRODUCTION:

Today, rapid speech transmission has become critical in many applications. With more quality being demanded by the end-user, and an increase in bandwidth usage, the delivery of audio and allied applications on demand cannot be left behind.

In this paper, we wish to present a new algorithm for speech compression using the frequency domain approach.

The same method has also been used in the compression of static images also ....etc

Abstract

This paper illustrates a novel method of speech compression and transmission. This method saves the transmission bandwidth required for the speech signal by a considerable amount. This scheme exploits the property of low pass nature of the speech signal. Also this method applies equally well for any signal, which is low pass in nature, speech being the more widely used in Real Time Communication, is highlighted here.

As per this method, the low pass signal (speech) at the transmitter is divi ....etc

Abstract
Bidirectional flexure analysis of functionally graded (FG) plate integratedwith piezoelectric fiber reinforced composites (PFRC) is presented in this paper. A higher order shear and normal deformation theory (HOSNT12) is used to analyze such hybrid or smart FG plate subjected to electromechanical loading. The displacement function of the present model is approximated as Taylor’s series in the thickness coordinate, while the electro-static potential is approximated as layer wise linear through the thickness of the PFRC layer ....etc

SUMMARY
Passive radar systems that exploit illuminators of opportunity, such as FM radio and television broadcasts, to
detect and track airborne targets have been under development for over a decade. This paper reviews efforts
to add radar imaging and target recognition capabilities to such systems. We discuss recent developments
along two parallel threads:
1) Target recognition via radar cross section (RCS) profiles: In this approach, databases of the RCS of
targets at different incident and observed angles are created using meth ....etc

The world is fast moving from a stage where steel and miles of railways were important, to a stage where, the size and complexity of information and communication systems will be the barometer of a country’s development. No country or individual can continue to afford to remain in isolation and ignore rapid developments in the field of information and communication technology. This so called “Information Society” has its genesis in the post industrial ar ....etc

THEORETICAL STUDY OF HIGHER ORDER NONCLASSICALITY IN INTERMEDIATE STATES



1 Introduction

A state of light is called nonelassieal, if its Glauber Sudarshan P function is negative or more singular than a delta function . In these situations quasi probability distribution P is not accepted as classical probability and thus one can not obtain an analogous classical state. For example, squeezed state and antibunched state are well known nonelassieal states. These two lowest order nonelassieal states have ....etc
