Understanding QAM Modulation Techniques by Asti Putri Rahmadini is a document available to read on EtoBox.
QAM combines PSK and ASK modulation techniques. It is primarily used for high-speed digital modulation. QAM modulation works by modifying the amplitude and phase of its carrier signal to transmit data as a combination of symbols. A QAM modulator encodes digital bits as symbols that are represented as constellation points, which are then used to modulate the amplitude and phase of a carrier signal. At the receiver, a QAM demodulator recovers the transmitted symbols by filtering and using decision circuits.
