What is PSK demodulator?

PSKDemodulator object demodulates a signal that was modulated using the M-ary phase shift keying (M-PSK) method. The input is a baseband representation of the modulated signal. To demodulate a signal that was modulated using the M-PSK method: Create the comm. PSKDemodulator object and set its properties.

How to demodulate PSK in Matlab?

z = pskdemod( y , M ) demodulates the input M-PSK signals y . M specifies the modulation order. z = pskdemod( y , M , phaseoffset ) specifies the phase offset of the M-PSK constellation. z = pskdemod( y , M , phaseoffset , symorder ) specifies the symbol order of the M-PSK constellation.

How does a BPSK demodulator work?

A BPSK demodulator consists primarily of two functional blocks: a multiplier and an integrator. These two components will produce a signal that corresponds to the original binary data. However, synchronization circuitry is also needed, because the receiver must be able to identify the boundary between bit periods.

What is the meaning of PSK?

phase shift keying: a digital data modulation system in which binary data signals switch the phase of a radio frequency carrier.
