The symbol map feature of the constellation object doesn't seem to do anything. In fact, you can leave it blank. The index of the constellation points is used to map the complex points to bits. The documentation leads one to believe otherwise. Working as intended? v/r, Rich ___

Hi all, What do people think of introducing a constellation object into gnuradio? It would hold the constellation points and also a decision-making function. New modulations could then be easily created by subclassing a constellation. It would also mean that the decision-making function for a gi
