Given that,
The output signal at the receiver must be greater than 40 dB.
Maximum amplitude = 1
Bandwidth = 15 kHz
The power spectral density of white noise is
Power loss in channel= 50 dB
Suppose, Using DSB modulation
We need to calculate the power required
Using formula of power
Put the value into the formula
For DSB modulation,
Figure of merit = 1
We need to calculate the input signal
Using formula of FOM
Put the value into the formula
We need to calculate the transmit power
Using formula of power transmit
Put the value into the formula
We need to calculate the needed bandwidth
Using formula of bandwidth for DSB modulation
Put the value into the formula
Hence, The transmit power is 3 kW.
The needed bandwidth is 30 kHz.
