A certain wireless channel has the following impulse response: h(t) = k1(t) + k2(t ) (a) Determine the frequency response of the overall system if the transmit and receiver lters are given by G(f) and C(f). (b) Determine the frequency response of the transmit and receive lters if the system is designed to completely mitigate the ISI by using an ideal Nyquist pulse. Assume that the channel is compensated solely at the transmitter. (c) Determine the frequency response of the transmit and receive lters if the system is designed to completely mitigate the ISI by using a raised cosine pulse with a roll-o factor = 0:5. Assume that the channel is compensated equally at the transmitter and receiver. (d) Determine the frequency response of the transmit and receive lters if the system is designed to completely mitigate the ISI by using a full raised cosine pulse. Assume that the channel is only compensated solely at the receiver.
