Linear Block Codes
n Check the previous code to see that it consists of
block of code words. Your message will be changed
to this format.
n Add any two code words to get a third one.
n A code with dmin is guaranteed to correct
(dmin 1) / 2 errors or detect dmin 1 errors.
n dmin = wmin (the smallest weight of the nonzero code
n Any linear block code can be systematic:
