Consider a CDMA system where transmitter A has the code 101010 and transmitter B has the code 111001. Assume that 1 is represented by +1V and 0 is represented by -1V. Show that the two CDMA codes (after mapping them to voltages) are orthogonal to each other. What is transmitted if A sends a bit of 0 and B sends a bit of 1? What did A and B most likely transmit if the received word is “-1 -1 -1 +1 +1 +1”?

Consider the queuing delay in a router buffer, where the packet experiences a delay as it waits to be transmitted onto the link. The length of the queuing delay of a specific packet will depend on the number of earlier-arriving packets that are queued and waiting for transmission onto the link. If the queue is empty and no other packet is currently being transmitted, then the packet's queuing delay will be zero. On the other hand, if the traffic is heavy and many other packets are also waiting to be transmitted, the queuing delay will be long. Assume a constant transmission rate of R = 600,000 bps, a constant packet-length L = 6,000 bits, and a is the average rate of packets/second. Traffic intensity I = La/R, and the Queuing delay is calculated as I(L/R)(1-1) for I< 1. Assuming that a = 24, what is the Queuing delay? Give your answer in milli seconds. Average queuing delay La/R 1
