The bits transmitted by four stations A, B, C and D are multiplexed using Code Division Multiplexing (CDMA). Assume A transmits a 1 bit, B transmits a 0 bit, C transmits a 1 bit, and D is silent. Assume the following are the chip sequences of the four stations, answer below questions: SA = (-1 -1 -1 +1 +1 -1 +1 +1); SC = (-1 -1 +1 -1 +1 +1 +1 -1) SB = (-1 +1 -1 +1 +1 +1 -1 -1); SD = (-1 +1 -1 -1 -1 -1 +1 -1) i) (2 points) What is the transmitted sequence? ii) (2 points) Show how the receiver determines station B’s transmission.
