Problem #3 Textbook problem # 17.8 "Consider a CDMA system in which users A and B have the Walsh codes (-11-11-11-11) and (-1-1 11-1-1 1 1), respectively. (a) Show the output at the receiver if A transmits a data bit 1 and B does not transmit. (b) Show the output at the receiver if A transmits a data bit 0 and B does not transmit. (c) Show the output at the receiver if A transmits a data bit 1 and B transmits a data bit. Assume the received power from both A and B is the same. (d) Show the output at the receiver if A transmits a data bit 0 and B transmits a data bit 1. Assume the received power from both A and B is the same. (e) Show the output at the receiver if A transmits a data bit 1 and B transmits a data bit 0. Assume the received power from both A and B is the same. (f) Show the output at the receiver if A transmits a data bit 0 and B transmits a data bit 0. Assume the received power from both A and B is the same. (g) Show the output at the receiver if A transmits a data bit 1 and B transmits a data bit 1. Assume the received power from B is twice the received power from A. This can be represented by showing the received signal component from A as consisting of elements of magnitude 1 (+1, -1) and the received signal component from B as consisting of elements of magnitude 2 (+2,-2). (h) Show the output at the receiver if A transmits a data bit 0 and B transmits a data bit 1. Assume the received power from B is twice the received power from A." (Hint: With different cases, the bits received at the receiver changes but the receiver codeword remains the same as that of A.)
