DBPSK - What does DBPSK stand for? The Free Dictionary

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. (Although the root concepts of QPSK and 4-QAM are different, the resulting modulated radio waves are exactly the same.) QPSK uses four points on the constellation diagram, equispaced around … See more Differential encoding Differential phase shift keying (DPSK) is a common form of phase modulation that conveys data by … See more The mutual information of PSK can be evaluated in additive Gaussian noise by numerical integration of its definition.
