Bipolar phase shift keying
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. The curves of mutual … See more BPSK (also sometimes called PRK, phase reversal keying, or 2PSK) is the simplest form of phase shift keying (PSK). It uses two phases which are separated by 180° and so can also be … See more Any number of phases may be used to construct a PSK constellation but 8-PSK is usually the highest order PSK constellation … See more Owing to PSK's simplicity, particularly when compared with its competitor quadrature amplitude modulation, it is widely used in existing technologies. The See more WebIn Phase shift keying (PSK), the phase of the carrier is modulated to represent the binary values. The carrier phase change between 0 and 𝜋 by the bipolar digital signal. Binary states “1” and “0” are represented by the positive and negative polarity of the digital signal. The simplest form of PSK is BPSK is shown in Figure 2.

WebIn Binary Phase Shift Keying (BPSK), the transmitted signal is a sinusoid of fixed amplitude. It has one fixed phase when the data is at one level and when the data is at the other level, the phase is different by 180 degree. A BPSK signal can be defined as Sepsk(t) = A Cos (21fet + fo if m(t) = 1) A m mt0 where m(t) is the binary information.
