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

A complexity reduction algorithm for an H.264 encoder is proposed. This comes at the cost of the number of increased macroblock modes and the complex mode decision procedure using the rate-distortion optimization . H.264 demands a high degree of computational complexity to be able to make use of the advantages of its new techniques. Experiment results in show that the proposed algorithm can reduce the encoding time by 29.67% on average and the rate-distortion comput ....etc

Performance analysis of channel estimation and adaptive equalization in slow fading channelPresented By:
Zhifeng Chen, Electrical and Computer Engineering, University of Florida
ABSTRACT
In our project, we first build up a wireless communication simulator including Gray coding, modulation, different channel models (AWGN, flat fading and frequency selective fading channels), channel estimation, adaptive equalization, and demodulation. Next, we test the ef ....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
Improved space“time coding for multiple-input and multiple-output orthogonal frequency division multiplexing is studied for wireless systems using QPSK modulation for four transmit and four receive antennas. A 256-state code is shown to perform within 3 dB of outage capacity (and within 2 dB with perfect channel estimation), which is better than any other published result without using iterative decoding. ....etc

Efficient Frequency Domain Selective Scrambling of Digital Video at java

Abstract:
Multimedia data security is very important for multimedia commerce on the Internet such as video-on-demand and real-time video multicast. Traditional cryptographic algorithms/systems for data security are often not fast enough to process the vast amount of data generated by the multimedia applications to meet the real-time constraints. This paper presents a joint encryption and compression framework in which video data are scrambled efficiently in the ....etc
