Hi
I'm trying to create a flow graph which transmits a direct sequence spread spectrum bpsk modulated signal.
- If '1' is the data bit then this is mapped to '1 1 1 1 0 1 0 1 1 0 0 1 0 0 0'
- If '0' is the data bit then this is mapped to '0 0 0 0 1 0 1 0 0 1 1 0 1 1 1'
1) I'm not exactly sure how to go about doing this mapping. Is there a pre-existing block that will allow me to do this or is this a block that I will have to create?
2) This is the flow that I'm trying to create.
Is there a bit to symbol conversion that needs to take place prior to the differential encoding?
Thanks
