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? 0 dB To = 0 1μs - 10 dB 5μs 100 dB Q.3) Consider the two-taps adaptive equalizer shown below used to minimize the effect of frequency selective multipath fading channel. a- Determine the autocorrelation function R b- Determine the estimated coefficients ŵ that achieves minimum error c- Find the value of the minimum mean square error MMSE d- If wo=0,w=0.8, what is the MSE Hint: let a vector P =E(dk Yk) yk=8 Z' |d=9 Yk-1=6 Wo=0.5 w=0.4 Xk Woyk+Wyk-1 (E) e error
