1) Are you SURE that's the Generator Matrix? Perhaps it's the Traspose of the generator matrix.

2) The Parity check Matrix is created by simply transposing the Generator Matrix and "OR"ing consecutive pairs of rows. For this reason, the Parity Check Matrix should have one row less than the Generator Matrix has columns.

If I actually knew anything about this sort of thing, I might be able to answer "C". You share your thoughts and maybe I'll do some more reading.
 
i am new to error correcting module...which i will be starting this september...so i was trying to read ahead on my own...and that question is from past exam paper of my uni so it must be correct...i tried one or two books ..but they are not that easy to understand ..and i don't know why they don't have solved problems in them...so far what i have understood (may not be correct) is if generator matrix is of size RxC then it means that codeing function takes in C bits and encodes it to R bits....and RANK of G must = number of Columns of G.....thats all i have managed to understand...may be u have some reading material (ur uni lecture note handouts etc) / links that can help me....also 1 or 2 simple example of check matrix for some simple Generator matrix.....thank you
 
thank you for those links ...i will hae a look at them ..thank you
