Problem 1. The Doppler PSD of a flat fading channel is given below. O dB -10 dB -10 dB -20 dB -20 dB fc fc+fm fc-fm fc- 0.3fm fc + 0.3fm The PSD of the transmitted signal is a strictly band-limited Rect function in “p' doma i.e. constant (=0 dB or 1) for –W<f<W, Zero otherwise. Also, W > 2fm Draw the received signal PSD. (Hint: take help from the one note describing spectra shaping effect due to Doppler shifts.)
