WebJun 3, 2024 · Definition: The DPSK stands for “Differential phase-shift keying”. It is one type of phase modulation used to transmit data by altering the carrier wave’s phase. What is … Phase-shift keying (PSK) is a digital modulation process which conveys data by changing (modulating) the phase of a constant frequency reference signal (the carrier wave). The modulation is accomplished by varying the sine and cosine inputs at a precise time. It is widely used for wireless LANs, RFID and … See more There are three major classes of digital modulation techniques used for transmission of digitally represented data: • Amplitude-shift keying (ASK) • Frequency-shift keying (FSK) See more Sometimes this is known as quadriphase PSK, 4-PSK, or 4-QAM.
