Hello,
I am simulating SAC-OCMDA system using my designed code. However I am having trouble with the concept of putting FBGs for “0” in code. Because my code contain six zeros when the number of subscribers is 4, and as I increase the number of subscribers, 0’s also increase.
My question is do we need to represent every 0 with an FBG, or we just have to represent the one’s that are close to 1 in the code.
Plus does the trailing bit matters because it also represent 1 for that matter?
