CDMA - Basic
Imagine a scenario where a sender and receiver using CDMA (Section 7.2.1 from the text) are exchanging data. Assume both the sender and receiver use a CDMA code of size 7, where M = 1, -1, 1, 1, 1, -1, 1.
Question List
1. Given the CDMA code above and the bit d=-1, what is the encoded output? Separate each value with a comma and no spaces
2. Given the CDMA code above and the output string: -1,1,-1,-1,-1,1,-1, what is the decoded bit value?
Solution
1. The encoded output is: -1,1,-1,-1,-1,1,-1
2. The original bit value is: -1
That's incorrect
That's correct
The answer was: -1,1,-1,-1,-1,1,-1
The answer was: -1
