Suppose a communications system that transmits a user's information, given by the following signal: . The system uses a carrierless dual sideband modulation, multiplying the signal by a 200kHz frequency cosenoidal carrier. At the receiver, the signal is multiplied by a 50kHz carrier and then passed through a (ideal) pass filter, with a bandwidth equal to 2kHz and centered at a frequency of 250kHz.

Consider a cellular system operating at 900 MHz where propagation follows free space path loss with variations from log normal shadowing with σ = 6 dB. Suppose that for acceptable voice quality a signal-to-noise power ratio of 15 dB is required at the mobile. Assume the base station transmits at 1 W and its antenna has a 3 dB gain.

Question-1) A signal with a bandwidth of 14 MHz is first passed through a low filter with a cut-off frequency of S MHz. Then the signal is sampled using the minimum sampling frequency required and each sample is coded with 8 bits.
