B: For MC$-$CDMA Downlink system, assume the number of users $K=2$ and the first transmitted

bits are $\text{'}11\text{'}$ and $\text{'}10\text{'}$ for the first and the second user, respectively.

Find the following:

$1-$ The transmitted sequence for the two users.

$2-$ The detected sequence for the first user, assume no channel effect.

Take the processing gain $=4$ and use Hadamard Matrix to generate the spread codes.
