For the IS - 95 CDMA transmitter shown below, we define the in-phase and quadtator resultant sequences or: I I (t) = D_n (t) times W_n(t) times C_(t) Q (t) = D_n (t) times W_n (t) times c_a (t) Write the equation for s_n (t) in terms of magnitude/phase form Show the I - Q cobstellation of this QPSK modulation and carrier phase transitions with respect to symbol pair transitions

Solution

a) Dn(t) * Wn(t) * Cit) + Dn(t) * W(t) *Ct(t) with

phase difference of pi/2
