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. Baud rate = … Read more
Data bits modulate (modify) a carrier signal Basic modulation techniques: amplitude frequency phase. Data bits are represented over the transmission channel by SYMBOLS Symbol rate is expressed in Baud (Symbols per Second) Modulation of a carrier is used to transmit data bits efficiently over the air interface The modulation process creates modulation symbols. A modulation … Read more
