Added my lab 3 files and data.
data/qam_with_sync1.npy contains my callsign in morse code followed by 1 second of zeros, a short pulse, zeros, our QAM signal, more zeros, and another short pulse.
Changed fs=48000 Hz to work with my interface.
Data was recorded with the SDR sampled at 240000 Hz.
The .npy files contain the raw fm modulated data received by the sdr.
test_qam.py is a skeleton file that we can use for testing. The main function will generate data, modulate and demodulate. We can eventually add BER tests as well.
qam.py will be have all of the actual QAM modulation and demodulation code. This way we can easily import it all when needed.
