Abstract:

Digital audio broadcasting, DAB, is the most fundamental advancement in radio technology since that introduction of FM stereo radio. It gives listeners interference - free reception of CD quality sound, easy to use radios, and the potential for wider listening choice through many additional stations and services.

DAB is a reliable multi service digital broadcasting system for reception by mobile, portable and fixed receivers with a simple, non-directional antenna. It can be operated at any frequency from 30 MHz ....etc

Hi I am Jahnavi.I want to do project in image processing. I have selected the main topic like error concealment. I need some matlab programs for that related topic. I em trying to implement IEEE paper published in 2006, Adaptive MAP Error Concealment for Dispersively Packetized Wavelet-Coded Images.

Abstract—In this paper, we present an adaptive maximum a posteriori (MAP) rror concealment algorithm for dispersively packetized wavelet-coded images. We model the subbands of a waveletcoded image as Markov random fields, and use the edge ....etc

ABSTRACT
In This Seminar An adaptive watermarking capacity analysis in the spatial domain and wavelet domain has to be present. The relationship between the watermarking capacity and the watermark detection error rate is also discussed. The discussion of watermark detection error rate will help us finding the ways to embed more watermark messages while keeping an acceptable detection error rate, it is useful for the design of the general algorithms of watermarking and detection. The watermarking system is analyzed based on the channel capacity ....etc

An Mp3 is an audio file format which is encoded from an Audio CD or other audio formats like wav, ram etc... Mp3 is the most popular format for music in the present world. Nowadays Mp3 players are available making Mp3's the best form of audio.

These Mp3 files are of different quality which is decided by the bit-rate of the file. Greater the bit-rate bigger the size of the file. These Mp3's have a great advantage of being able to store the various information about the audio file, namely the artist, album , year etc.. This is achieved with th ....etc

Abstract

Here, students learn how error correction coding makes wireless communications more robust in the presence of noise. In the laboratory, the students work in Matlab to code two simple error correction schemes, and simulate their use in a wireless channel. In the process, they learn concepts such as bit error rate, and see the trade-off between processing time and robustness.

The PLC Cycle

-The PLC is initialized internally when the power is turned on
-If no error are detected, the overseeing processes , program execution, I/O refreshing, and peripheral device servicing are executed consecutively (cyclically)
-The average cycle time can be monitor from a Peripheral Device

Self-diagnosis Functions

-The PLC is equipped with a variety of self-diagnosis function to help identify and correct errors that might occur and reduce down time

Introduction

The packet transport service provided by representative packet-switched networks, including IP networks, is not reliable and the quality-of-service cannot be guaranteed. Packets may be lost due to buffer overflow in switching nodes, be discarded due to excessive bit errors and failure to pass the cyclic redundancy check at the page link layer, or be discarded by network control mechanisms as a response to congestion somewhere in the network. Forward Error Correction coding has often been p ....etc

Introduction

Sensors integrated into structures, machinery, and the environment, coupled with the efficient delivery of sensed information, could provide tremendous benefits to society. Potential benefits include: fewer catastrophic failures, conservation of natural resources, improved manufacturing productivity, improved emergency response, and enhanced homeland security . However, barriers to the widespread use of sensors in structures and machines remain. Bundles of lead wires and fiber optic ....etc
