A vehicle moves with a velocity v(t) as shown in Fig. 2. Determine the average crossing rate and fade duration over 100 seconds interval. Assume p = 0.1 and ignore large scale fading. (6 marks) (b) An application that requires a power outage probability of .01 for the threshold P. = -80 dBm. For Rayleigh fading, determine the required average signal power?
