Question

Consider sender 2 in Figure below, a) What is the sender's output to the channel if the sender's 2 CDMA code were (1, -1, 1, -1, 1, -1, 1, -1) (before it is added to the signal from sender 1), Z_{i,m}^2? b) Suppose that the receiver in the Figure wanted to receive the data being sent by sender 2. Show (by calculation) that the receiver is indeed able to recover sender 2's data from the aggregate channel signal by using sender 2's code given in part a.
