CDMA - Advanced
This time, assume there are 2 senders whom interfere with eachother and
that the interfering transmitted bit signals are additive. The value received at a
receiver, however, is now the sum of the transmitted bits from all senders.
Assume that sender 1 has a CDMA code of (-1, 1, 1, 1, -1, -1, -1, 1) and sender 2 has a CDMA code of (1, -1, -1, 1, -1, -1, -1, -1) and their combined output is: (2, -2, -2, 0, 0, 0, 0, -2)
Question List
1. Assuming you are receiver 1, what is the decoded bit? If it can't be done, answer with 'n/a'
2. Assuming you are receiver 2, what is the decoded bit? If it can't be done, answer with 'n/a'
Solution
1. The decoded bit is: -1 for sender 1
2. The decoded bit is: 1 for sender 2
That's incorrect
That's correct
The answer was: -1
The answer was: 1
