performance of a digital transmission in the presence of the error correction coding

This M-file gives you the importance of digital transmission with the presence of the correction

Is to study the improvement of digital transmission for BER, the correction code block with the control matrix is defined by:
H=[1 0 1 1 0 0;1 1 0 0 1 0;0 1 1 0 0 1];
with:
length code : n=6.
length information : k=3.
