An automobile moves with velocity v(t) shown in Figure 1. The received mobile signal experiences multipath Rayleigh fading on a 950 MHZ CW carrier. What is the average crossing rate and fade duration over the 100 s interval? Assume p=0.2 and ignore large-scale fading effects. v(t) * (m/s) 20 Vehicle speed vs time 0 20 Figure 1 80 100 time (s)
