    (a) Graph the theoretical number of users of a CDMA system with a data rate of 9.6 kbs and 14.4 kbs while varying the Voice activity factors from 10% - 100%
    (b) Create the Walsh code matrix for a W16.
    (c) For IS-95, on the forward link, list the Walsh code assigned to the various logical channels (hint: there are 64 Walsh codes)
