Hi,
I'd like to start off with a project of transmitting and receiving audio signal using 4-QAM modulation.
(Later, I'd move to transmitting pictures and video, therefore I'd like to use 4-QAM).
The blocks would
Microphone ---> PIC ---> QAM Modulator ---> Transmitter ---------> Receiver ---> QAM Decoder ---> PIC ---> Speaker
I'd like to avoid doing by myself the FFT in the PIC.
Should I use additional module between the PIC and the QAM Modulator, that will perform the FFT and pass it to the QAM Modulator?
Thank you.
