Hi all,
I'm studying information theory but one thing I can't seem to work out.
I know that given a linear code C and a generator matrix M I can work out all the possible codewords of C.
However I do not understand:
- What a parity check matrix is http://en.wikipedia.org/wiki/Parity-check_matrix
- How to make a parity check matrix from a generator matrix
I'd really appreciate any pointers!
Thanks!
