8.) Consider a CDMA system in which users A and B have the Walsh codes (-1 1 -1 1 -1 1 -1 1) and (-1
8.) Consider a CDMA system in which users A and B have the Walsh codes (-1 1 -1 1 -1 1 -1 1) and (-1 -1 1 1 -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 1. Assume the receiver 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 receiver 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 receiver 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 receiver 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 receiver power from B is twice the received power from A. This can be represented by showing the received signal component 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 receiver power from B is twice the received power from A
