An impulse response contains two rays: one with a delay of 8 us and of
amplitude of -120 dBm, the other with a delay of 11 us and of amplitude
of -117 dBm.
(i) Sketch the Power Delay profile for this channel.
(ii) What is the delay spread of this channel and the coherence
bandwidth?
(iii) Justify your results if an equalizer will be required to transmit a
300 ksymbol/s stream.
