For the communications channel described in the previous question, what level of power below the average power does this R/Rrms value correspond to (in dB) Suppose the EIRP of the basestation is decreased by 2 dB. This will decrease the value of Rrms but not R. What will be the new value of R/Rrms?

Consider the power delay profile given below. If you see two pictures, they should be the same. if you do not see any pictures, the power delay profile can be described as follows: There are 3 spikes: a 0 dB spike at tau=0us, a -7 dB at tau = 2us, and a -10dB spike at tau = 3us Assume that a signal with a 50 kHz bandwidth is being transmitted at 2 GHz through this channel to a mobile. What is the mean excess delay for this channel? What is the rms delay spread for this channel? What is the maximum excess delay (8 dB) for this channel? What is the 90% coherence bandwidth for this channel? Is this a flat fading channel relative to 90% coherence for the signal described above (yes or no)?
