The 11001100 code is the third column of the 8×8 Hadamard code (you could just use the code “hadamard(8)” in Matlab to see this).
I don’t understand your question. Based on the number of users, you can choose hadamard code length (for example for 8 users, you can use each of the rows or columns of the 8in8 hadamard matrice as a code for one user). If this is not your answer, please elaborate more on your question.
