Doppler spectrum Consider a mobile unit with an antenna characterized by again G(). If the distribution of the power of the reflected signal is p(), then within a differential angle d, the normalized received power is G()p()d. This power is equal to the differential variation of the received power with frequency, S(f )df, where S(f ) is the Doppler spectrum. Determine and plot S

(f) for the transmitted unmodulated carrier when an omnidirectional antenna is used with G()¼1,  is uniformly distributed, and the total power of the received signals is 22s
