A channel has the following power delay profile.
a) Determine the mean excess delay time and the rms delay spread.
b) If 16-QAM is used, what is the maximum possible bit rate without the need of an equalizer? Suggest a method to double this bit rate without needing an equalizer.
c) If a mobile is traveling through the channel with a velocity of 100 Km/hr, what is the time at which the channel could be considered stationary if the carrier frequency is 900 MHz?
