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 ...

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 ...

Frequency Modulation (FM) sounds simple at first, but understanding the electronics behind modulation and demodulation of an FM signal can be confusing. We’ve covered the basics before, ...

Later on they have implemented a QPSK modulation technique using reversible logic and the QPSK modulator unit will be modelled using HDL code and simulation will be done by ModelSim 6.0 ...
