What is BPSK modulator?

Binary Phase-shift keying (BPSK) is a digital modulation scheme that conveys data by changing, or modulating, two different phases of a reference signal (the carrier wave). The constellation points chosen are usually positioned with uniform angular spacing around a circle.

How does BPSK modulation work?

The modulation of BPSK is done using a balance modulator, which multiplies the two signals applied at the input. For a zero binary input, the phase will be 0° and for a high input, the phase reversal is of 180°. Following is the diagrammatic representation of BPSK Modulated output wave along with its given input.

How to modulate BPSK in Matlab?

bpskmodulator = comm. BPSKModulator creates a modulator System object™ to modulate input signals using the binary phase shift keying (BPSK) method. bpskmodulator = comm. BPSKModulator( Name , Value ) creates a BPSK modulator object with each specified property set to the specified value.

What are the phases in BPSK?

Binary phase-shift keying (BPSK)

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.
