What is the carrier frequency in the modulation?
Carrier frequency is defined as the frequency of a carrier wave, measured in cycles per second, or Hertz, that is modulated to transmit signals.
What generates the carrier frequency?
The carrier frequencies generated by oscillators at the transmitter and the receiver are usually not identical. The difference between the two carrier frequency is referred to as the carrier frequency offset (CFO).
What is quadrature carrier multiplexing?
A quadrature-carrier multiplexing, or quadrature-amplitude modulation (QAM), system enables two DSB-SC modulated waves, it results from the application of two independent message signals and occupies the same transmission bandwidth, and yet it allows for their separation at the receiver output.
