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

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

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

Introduction:-

As more and more information is relayed over and stored on the internet, it becomes increasingly important to scrutinize and determine the identity of those who access that information. In the modern world, the importance of information security has attained an all time high. Authentication refers to the act of verifying the identity of an entity or an object. In the world of Information security, it refers to a method of reliably identifying a person / entity as authorized to access certain information. ....etc

Abstract


Aim of the project is to implement the Security features that can avoid Data Dictionary attacks in both the server and transmission part. The first part is to control the data dictionary attacks that occur in direct internal way to the server. Graphical based password authentication is implemented where Pixel co-ordinates are fixed as the password. CCP (cued click points) in added for more security. The user can click the pixel points and login to the server. The user is permitted to click the pixel ....etc

Abstract
A good online dictionary can be fast, efficient, and more current than print editions. Better still, consulting an online dictionary may be more convenient than unearthing the cumbersome desk dictionary from a growing mound of journals and manuscripts. Whether print or online, dictionaries are helpful only if they include the words that users are seeking. Unfortunately, many dictionaries available on the Web are not so good. After selecting 15 uncommon”but not quite obscure”words from various fields of ....etc
