Hadamard Sequence

There is a very simple way to create a set Hadamard codes, it is called the the recursive technique.

Below is an example of how four sequences of code are created from the two sets using the above formula.

So above shows four sequences of code and three lines of code are used for characteristics, synchronization and paging. Which means that a four chip spreading code, like above, will only have one available slot for a user.
