16 PSK

16 PSK 16-PHASE SHIFT KEYING (16-PSK): Angle modulated with constant amplitude digital modulation. 4 bits encoded forming and producing 16 different outputa are possible. N = 4, M = 2N = 24 = 16 Therefore 16 output phases will be produced Each channel bit rate is...

8 PSK

8 PSK 8-PSK modulation basics or multilevel PSK modulation which is a type of digital modulation based on carrier phase change. In Phase Shift keying modulation or PSK modulation phase of carrier is changed according to the digital data. It is digital modulation...

QPSK

QPSK Quadrature phase-shift keying (QPSK) Constellation diagram for QPSK with Gray coding. Each adjacent symbol only differs by one bit. Sometimes this is known as quadriphase PSK, 4-PSK, or 4-QAM. (Although the root concepts of QPSK and 4-QAM are different, the...

BPSK

BPSK BPSK (also sometimes called PRK, phase reversal keying, or 2 PSK) 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...

Phase Shift Keying

Phase Shift Keying Phase shift keying (PSK) is a digital modulation scheme that conveys data by changing, or modulating, the phase of a reference signal (the carrier wave). Any digital modulation scheme uses a finite number of distinct signals to represent digital...

Minimum Shift Keying

Minimum Shift Keying In digital modulation, minimum-shift keying (MSK) is a type of continuous-phase frequency-shift keying that was developed in the late 1950s and 1960s.Similar to OQPSK, MSK is encoded with bits alternating between quadrature components, with the Q...
