Hi I would like to know can anyone explain to me is there any way to figure out the appropriate carrier frequency(For modulation) for a given signal frequency response and bandwidth and channel frequency response? I mean what criteria determine the carrier frequency ? I know it should be
higher than signal frequency but by how much ? What are the techniques to find the best carrier frequency range?
For example assume we have signal frequency between 0-150 kHz and channel bandwidth 0-100kHz and I would like to modulate (lets say BPSK) the signal by a carrier,
what methods I can use to find the best carrier frequency ?
