Problem solving

[raviserene]

Hi there hope u can help me out. I am a EEE student. This is a doubt from my paper communication & network transmission

please help me out. The following are the 2 problems:

1.consider a(7,4) cyclic code with generator polynomial g(x)=1+x+x3. let data word m=(1010). find the corresponding systematic code

2. let U be a (7,4) cyclic code with g(x)=1+x+x3. find a generator matrix G for U and find the code eword for m=(1010)

wow, its nice you have formed your Q nicely, but unfortunately, as much as I wanted to help, I have not taken Communications as a subject. I can tell you one thing though.

Take out the keywords like:

Cyclic code, Systematic Code, Generator matrix, Code eword, Generator polynomial etc

Now try this in google, as I have tried... "cyclic code generator polynomial" and this is what I found:

First link to a PDF lecture file on Cyclic Codes and Generator Matrices...

nice, thanks for the links! Ive yet to take this subject.. sounds hard though are the problems about encoding data or something? maybe coding theory.
