PDF-INVITED PAPER An Introduction to Adaptive QAM Modulation Schemes for Known and Predicted

By Arne Svensson Fellow IEEE ABSTRACT A major disadvantage with fixed modulation nonadaptive on channels with varying signaltonoise ratio SNR is that the biterrorrate BER probability performance is changing with the channel quality Most applications.

The sampling rate should be at least twice the bandwidth of the signal, in order to fully reconstruct the signal.. nalhareqi-2013. 1. Standard Amplitude Modulation (AM). nalhareqi-2013. 2.
