Dear all, I am trying to implement a QAM in 56303EVM. I have a weird problem that confuses me. For creating the necessary sine and cosine signals I am using a 16 valued lookup table. When I sent lookup values to the codec (without modulation) I get a nice, smooth sinus/cosinus signals. So my codec is working okey. However when I start modulating the input signal according to constellation ...
