Preamble-based SNR Estimation in Frequency Selective Channels for Wireless OFDM Systems
AIM:
To develop an efficient algorithm for the average SNR estimation in wireless OFDM systems.
BACK GROUND:
• OFDM is a multicarrier modulation scheme that provides strong robustness against inter symbol interference (ISI) by dividing the broadband channel into many narrowband sub- channels in such a way that attenuation ....etc

ABSTRACT :

Orthogonal frequency-division multiplexing is a popular method for high-data-rate wireless transmission. OFDM may be combined with multiple antennas at both the access point and mobile terminal to increase diversity gain and/or enhance system capacity on a time-varying multipath fading channel, resulting in a multiple-inp ....etc

Preamble-based SNR Estimation in Frequency Selective Channels for Wireless OFDM Systems
Synopsis
Introduction
There are two general categories of average SNR estimators. Data-aided (DA) estimators are based on either perfect or estimated knowledge of the transmitted data. However, a certain portion of data is needed for estimation purposes, which reduces bandwidth efficiency. Blind or in-service estimators derive SNR estimate from an unknown information-bearing portion of the received signal preserving efficiency a ....etc

Abstract:
CYBER CRIME has nowhere been defined in any statute /Act passed or enacted by the Indian Parliament. The concept of cyber crime is not radically different from the concept of conventional crime. Both include conduct whether act or omission, which cause breach of rules of law and counterbalanced by the sanction of the state .particularly those surrounding hacking, copyright infringement through warez, child pornography, and child grooming. There are also problems of privacy when confidential infor ....etc

INTRODUCTION

From its origin more than 25 years ago, Ethernet has evolved to meet the increasing demands of packet-switched networks. Due to its proven low implementation cost, its known reliability, and relative simplicity of installation and maintenance, its popularity has grown to the point that today nearly all traffic on the Internet originates or ends with an Ethernet connection. Further, as the demand for ever-faster network speeds has grown, Ethernet has been adapted to handle these higher speeds and the concomi ....etc

Introduction:
In this 21st century we required a multi functional system to operate on different platforms, which can access data easily, the main purpose of a Heterogeneous server is to establish a Heterogeneous network that can connect computers and other devices with different operating systems and/or protocols. For example, local area networks (LANs) that connect Microsoft Windows and Linux based personal computers with Apple Macintosh computers are heterogeneous. The word heterogeneous network is also used in ....etc
