Body:
I’m working on the IQmod example in MATLAB and attempting to generate a 4FSK signal for transmission at 150 MHz. However, I’m unclear about how to control the center frequency of the transmitted signal.
Current Approach:
I’ve tried using the center frequency option in the inport block, but it doesn’t seem to affect the transmission frequency.
The iqmodulator block offers a local Oscillator option, but its purpose in setting the center frequency isn’t entirely clear.
My Question:
How can I properly set the center frequency to 150 MHz for transmitting the 4FSK signal using the IQmod example? Should I be modulating the baseband signal with a carrier at 150 MHz before feeding it to iqmodulator? Or is there another approach within the existing structure?
Additional Information:
I’m using a sampling rate of 1 MHz for the IQ data.Body:
