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.

Thanks in advance

We have done 3 bit error correction for 8 bit orthogonal codes. but how can we detect 7 bit errors in the case of 16 bit orthogonal codes as in general we can detect (n/2-1) bits? ....etc

HAMMING CODE GENERATION AND ERROR DETECTING AND CORRECTING



INTRODUCTION:

In this lab we will review the steps to create and compile a project on programmable logic using ISE and we will introduce the required steps to download the project into a chip. The programmable device you are you going to use is the Coolrunner CPLD. In front of you is a black plastic board with two circuit boards on it. There should be ....etc

Enhancing Iris Biometric Recognition System with Cryptography
and Error Correction Codes: A Preliminary Study

Abstract
Major challenge on iris and most biometricidentifier is the intra user variability in the acquired identifiers.Iris of the same person captured in different time may differ dueto the signal noise of the environment or the iris camera. In ourproposed approach, Error Correction Code, ECC is thereforeintroduced to reduce the variability and noise of the iris data. Inorder to find best system performance, the approach ....etc

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

Error Detection and Correction

Many factors can lead to errors during transmission or storage

When binary information is sent across a physical channel such as wire, coax cable, optical fiber or air, there is always the possibility that some bits will be received in error due to interference form other sources; or, due to signal attenuation because of long distances or e ....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
