Question No. 2: Assume that two senders, A and B, want to send data to C, with the following unique and orthogonal key sequences: key Ak=101101 for sender A, key BK= 101010 for sender B. Sender A wants to send the bit Ad=0, sender B sends Bd=1. Considering that both signals will be transmitted at the same time using the same frequency, find the following: 1- The spread signal code for sender A. 2- The spread signal code for sender B. 3- The signal code received by receiver C. 4- The data values that C detects from A and B signals
