I went through the algorithm on Wikipedia and also understood its http://stackoverflow.com/questions/10703643/hamming-code-error-detection working as described in the thread How does the Hamming code work? But the code below uses some kind of sum of the parity bits in order to detect which bit is the error. Can someone please explain how exactly the sum can be used to detect the error bit? code: #include allUploadSign inJoinBooksAudiobooksComicsSheet MusicERROR DETECTION AND CORRECTION USING HAMMING CODE Uploaded by Arunabh NagBitCompilerLinuxError Detection And Correction26K viewsDownloadEmbedDescription: Project ReportSee MoreProject ReportCopyright: Attribution Non-Commercial (BY-NC)Download as DOC, PDF, TXT or read online from ScribdFlag for inappropriate content https://www.scribd.com/doc/25715552/ERROR-DETECTION-AND-CORRECTION-USING-HAMMING-CODE PROJECT REPORT ONERROR DETECTION ANDCORRECTION USING HAMMINGCODE CONTENTS 1.Company Profile2.Introduction3.Requirements Hardware requirements Software requirements Operating system Language4.Modular Diagram5.Coding6.Snapshots7.Scope and Objectives8.Conclusion9.Proposed enhancements10. Bibliography OPEN http://aqdi.com/articles/using-the-golay-error-detection-and-correction-code-3/ SOURCE SOFTWARE VERSUS CLOSEDSOURCE SYSTEM Open source software is currently one of the most debated phenomena in thesoftware industry, both theoretically and empirically. At the most basic level,the term error detection open source software simply means software for which the source codeis open and available. The source code is the program in which a software isoriginally written. A software is said ”open” when its source code can be read(seen) and written (modified) by everybody. Availability implies that anybodycan acquire the code either free of charge or for a nominal error detection and fee (usually mediaand shipping charges or online connection charges).In recent years, the growth and development of the open source movementhas been boosted by the Internet: today, making a source code available canbe as simple as posting it on the World Wide Web or in an online newsgroup.Furthermore, making the software open is also extremely simple, i.e. place norestrictions on how the software is actually used or by whom.Typically, open source software has been extremely successful in those segmentsof the market where the potential purchasers are ”sophisticated users”,i.e. system andserver administrators or more generally those that are experiencedin handling computers and that, for this reason, are well aware of allvarious packages available. Just to take a relevant example, the open sourcesoftware Apache is currently the most popular software for web servers; itsmarket share is about 60% of the total, more than two times larger thanMicrosoft, its ”closed source” commercial rival. Two other examples of well establishedopen source softwares are Sendmail, the dominant messaging serviceprogram for routing and handling email by email servers and L The code exhibited in this article has been adapted and flown on the UKube-1 satellite! For more information on the UKube-1, see this article. This is the scene: Smoke wafts slowly in the darkened room, as with a mind of its own. Seedy characters sit at a dirty table under a naked bulb. At the focus, a Ouija board. Surrounding are piles of paper -- data stacked upon data upon data, casting stark shadows. A sheet is snatched, examined, a scribble and it's back to the pile. Occult bookies hard at work? No, error correction! Well, that was my vision of it, until I was forced to bone-up for a recent communications project. I found out that error correction is not really like what you see in the movies, smoky mirrors, crystal balls, and evil mathematicians. If your vision of error correction is something to be avoided, I would like to help you change that image. Most engineers are familiar with basic methods to verify the integrity of data transmitted over noisy communications channels. Simple checksums and cyclic redundancy checks (CRCs) are the most popular. Presented here is a related coding technique by which errors can not only be detected, but removed from received data without retransmissions. This code bears the name of its discoverer, Marcel J. E. Golay. The first reference to his work is a note he published in a 1949 Bell technical journal1. Then, there was much activity in information coding techniques spurred by Claude Shannon's 1948 landmark work, The Mathematical Theory Of Communication. The codes that Golay discovered can enhance the reliability of communication on a noisy data link. Before we proceed, a note of caution. The theory of error detection and correction is deep (but not necessarily dark), as you can verify from any of the references cited. This article is intended only to give a brief overview of one of the many codes available. We will not dwell on the mathematical details or terse comparisons error correction techniques. If your system design calls for error correction methods, the C program fragments here may help you evaluate the Golay code. Just keep in mind that this is not a theoretically thorough treatment of this almost bottomless, fascinating subject. For that, see the references, and be sure you have a fresh pot of coffee on hand because you're goiError Detection And Correction Codes In Digital Electronics
