Is it possible to do rudimentary error correction with CRC?

阅读更多关于 Is it possible to do rudimentary error correction with CRC?

问题 I know the whole intention of using CRC is to do error detection, but I heard someone state that it can be used to do basic error correction in addition to error detection. I was curious if this was the case, and if so, how powerful is it? I mean, we usually refer to CRC as capable of performing x-bit detection, but I'm curious if it is capable of performing x-bit correction. If so, how does this work? Thanks. 回答1: It is possible to do single-bit error correction with a CRC. Assume one has a

Error correcting codes for packet loss (UDP)

阅读更多关于 Error correcting codes for packet loss (UDP)

问题 I have no real idea what to look for, since all I get with "Error correcting codes" is stuff related to cases where you don't know the location of the error. Thus those codes are much more complicated an inefficient than I need them to be. In the following, note that bits are equal to packets (because only a whole packet can be missing, thus the bit analogy fits very well). Are there ECCs that take into account that you already know WHICH k -bits are missing and only provide you with a way to

Getting most likely documents of the query using phonetic filter in solr

阅读更多关于 Getting most likely documents of the query using phonetic filter in solr

问题 I am using solr for spell checking/ query correction . I have added solr.PhoneticFilterFactory and solr.NGramFilterFactory in fieldType to perform spell checking . It is working fine but here the problem is that I am getting number of documents of the query. I need only most likely words/documents or in similar words, we can say that nearer words/documents to the query . Snippet of schema.xml : <fieldType name="textSpell" class="solr.TextField" positionIncrementGap="100"> <analyzer type=

Can you enable Error Corrections for C# in Visual Studio?

阅读更多关于 Can you enable Error Corrections for C# in Visual Studio?

问题 Visual Studio 2010 contains error corrections for VB programmers, for example, it will allow you to import a namespace or generate a stub class/method where you get compiler errors. For example, if you type: Dim mm As MailMessage without an Imports System.Net.Mail , you'll get a handy little tooltip that just allows you to import the namespace with a single click. I've recently switched to C# developing, and I really miss this little tool - if you're not sure of a namespace you have to go

Basic Reed-Solomon Error Correction Question

阅读更多关于 Basic Reed-Solomon Error Correction Question

问题 Does Reed-Solomon error correction work in an instance where there is a dropped byte (or multiple dropped bytes)? For example, let's say it's a (12,8) Reed Solomon code, so theoretically it should be able to correct 2 errors (or 4 erasures if the position is known). But, what happens if only 11 (or 10) bytes are received and one doesn't know which byte(s) were dropped? Will Reed-Solomon error correction work? Thanks, Ben 回答1: RS decoding for erasures requires the position of the symbols

Closed 5 years ago . How does ECC (error correction codes) for burst error correction work (disk drive style)? It is either a curse or blessing, but often my brain tries to solve technical problems in my dreams. Sometimes it does. Like last night, my brain demanded to understand how to design an ECC
