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…
-
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. -
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? -
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
