Quadrature Amplitude Modulation (QAM) in Wimax
QAM symbols are represented by the carrier signal being transmitted with specific phase (90°)/amplitude (dictated by the message), for finite periods of time. QAM constellations (patterns) 2 QAM (Binary PSK – BPSK) Two symbols are defined (1 amplitude; 2 phases) Every symbol transmitted over the transmission channel represents (carries) 1 message bit.
