We consider discrete-time (DT) systems S in which a DT input is first transformed to a continuous-time (CT) format by phase-amplitude modulation, then modified by a non-linear CT dynamical ...

A new frequency-operated demodulator is described which does not respond to amplitude modulation. These results are achieved by making use of a controlled oscillator at the receiver which ...

This is the reverse modulation loop demodulation QPSK signal is the key, but also the most difficult to grasp the actual. Based on the above three kinds of carrier recovery loops, it can be seen that ...
