Assume that the data rate on a link if a user is using the $$full bandwidth$$ is $100$ Mbps$.$

Assume that the bandwidth is $200$ MHz$.$ That is$,$ each Hz of bandwidth can support $0\mathrm{.}5$

bits$/$s$.$ The data rate supported by one unit of bandwidth is called the spectral efficiency and

this is $0\mathrm{.}5$ bps$/$Hz for this link. Show in a figure how four users may share this bandwidth $($a$)$

in frequency and $($b$)$ in time. Assume that time slots are $100$ms long. You have to clearly

label the axes and the units for both cases. Note that this is the ideal case. In most

situations, a buffer is required to separate users in time or frequenc
