I am new to this forum. I have some issue regarding the generator matrix. Please can some body can explain me "How to get Codebook from Generator matrix?"
I have found similar thread but answer in there is not very clear for me (generator matrix).

Generator matrix has 3 code words.
Then codeboke should has 8 code words.

So cot the codebook I already have 4 code words. (All zero vector and 3 vectors in G)

I can get another 3 by adding (1+2),(1+3), (2+3)

So now I have all together 7 code words.

How to get the Last???
