Our PSK example in equations (5.75a) and (5.75b) above is shown as example in Figure 5-9(a). Since M = 2, i.e. that we have a binary system, this modulation type is called binary phase shift keying ...

phase shift keying 1 Articles ... implementation uses a phase detection circuit or something ... build an analog BPSK31 demodulator and hit upon the idea of doing this with amplitude demodulation.

Taking it one step further, several groups demonstrated binary digital modulation schemes (binary phase-shift keying (BPSK) and binary frequency-shift keying (BFSK)) with graphene transistors on ...

This demodulator is suitable for the quadrature phase-shift keying (QPSK) modulator previously published by the same author, "Novel Low-Cost QPSK Modulator Needs No Adjustments" (electronic design ...

According to the paper, the team demonstrated reception of: binary phase-shift keying, quadrature phase-shift keying and quadrature amplitude modulation: “The results show that we can now interrogate ...
