WebPhase Shift Keying (PSK) is the digital modulation technique in which the phase of the carrier signal is changed by varying the sine and cosine inputs at a particular time. PSK … WebMar 1, 2011 · This script simulates the Binary Phase Shift keying. Since BPSK is a digital modulation scheme, you can modulate as many bits as you want. however, I have only simulated it for few bits, so that the results are visible. This is code for BPSK only, means it can only modulated two digital states on two different phases.

PSK31 - Wikipedia

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 termed 2-PSK. It does not particularly matter exactly where the constellation points … See more Any number of phases may be used to construct a PSK constellation but 8-PSK is usually the highest order PSK constellation deployed. With more than 8 phases, the error-rate becomes too high and there are better, though more complex, modulations available such as See more Owing to PSK's simplicity, particularly when compared with its competitor quadrature amplitude modulation, it is widely used in existing technologies. The wireless LAN standard, IEEE 802.11b-1999, uses a variety of different PSKs depending on the … See more WebQuadrature Phase Shift Keying (QPSK) is a form of Phase Shift Keying in which two bits are modulated at once, selecting one of four possible carrier phase shifts (0, 90, 180, or 270 degrees). QPSK allows the signal to carry twice as much information as ordinary PSK using the same bandwidth. WebBinary Phase Shift Keying (BPSK) The first modulation considered is binary phase shift keying. In this scheme during every bit duration, denoted by T, one of two phases of the carrier is transmitted. These two phases are 180 degrees apart. This makes these two waveforms antipodal.
