Quadrature phase shift keying (QPSK) and binary phase shift keying (BPSK) modulators are used to change the amplitude, frequency, and/or phase of a carrier signal in order to transmit information.

In contrast to the sophisticated implementation of Binary Phase Shift Keying (BPSK) transmitter using Application Specific Integrated Circuit (ASIC), mixer, and Local Oscillator(LO) for carrier signal ...

The relationship between saturation, intermodulation distortion and spectral regrowth is important in the design and test of RF power amplifiers. A binary phase shift keyed (BPSK) signal using a 1010 ...

Update (July 29, 2013): The spectrum recorded by the German Aerospace Center researchers appears to be consistent with a combination of BPSK(1) and BOC(5,2) modulation. This is the signal structure ...

We introduced the underlying mathematics of symbol error analysis for digital communication systems in August, using the simplest case of BPSK. We concentrated on the ...
