I have a simple 16QAM project. I want to do audio but for right now I
have a signal source "constant" input to the QAM module. I am trying to
display the constellation diagram but it's not displaying what I think
it should. I have a few questions....
1) I would think that inputing a constant value into the QAM module would
produce a single point, it doesn't, it puts up a grouping of 8 points of the 16
possible locations. I am trying to verify the input verses
output.
2) The QAM module expects a "char" type which I assume is 4 bits. If I
have 8-bit (byte) data from a audio source, how do I feed the QAM
module?
3) How do I setup a QAM-Demod module to produce an output? I don't seem to get
anything out that resembles the input.
Thanks...Tom
