The modulation scheme 16FSK is pretty unusual ... 4QAM represents two bits per symbol and is generally known as QPSK. ... It does the modulation and demodulation digitally with DSP so you ...

The High Data Rate Demodulator IP core can demodulate BPSK, QPSK, offset-QPSK (OQPSK), 8PSK and 16QAM modulation schemes, all to a high performance level and at high symbol rates. The demodulator is ...

A broadcaster could also choose to use two modulation schemes; simultaneous use of TC8PSK and QPSK realizes a hierarchical transmission scheme that extends the broadcaster's service availability.

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 ...

Remarkably, both modulation schemes can be realized with just 1 and 2 all-graphene transistors, respectively, representing a drastic reduction in circuit complexity when compared with conventional ...

The performance of the modulation techniques-Binary Phase Shift Keying (BPSK) and Quadrature Phase Shift Keying (QPSK) are studied in the Nakagami channel and the Rician Channel.
