A DSC-SC modulated signal is transmitted over a noisy channel, with the power spectral den- sity of the noise as shown in Fig. below. The message bandwidth is 4 kHz and the carrier frequency is 200 kHz. Assume that the average received power of the signal is -80 dBm, and determine the output signal-to-noise ratio of the receiver. -400 SN(f) (W/Hz) 10-18 0 400 f (kHz)
