In the proposed scheme, the received signal is
demodulated using binary phase shift keying (BPSK) demodulator.
The digital frequency signals in the upper part are the three sensors' signals and one synchronous signal in the transponder; and the digital frequency signals in the lower part are the
demodulated and shaped signals in the reader.
Taking I plane, for example, with the I vector [x.sup.I.sub.residual,i] of residual signal and the corresponding center line value a shared between the sender and the receiver, the secret message bits can be
demodulated with (14).
(26), the k-th symbol's PS is
demodulated. Then according to the Maximum Likelihood (ML) decision rule, the polarization constellation point [P.sub.k] can be classified from [P.sub.k.sup.R].
A view of windows with values of
demodulated bits and decoded text of the message received.
In this method, first, a receiving AM radio signal containing HV noise is quadrature
demodulated. Next, a replica signal of the noise is generated by using the noise signal in the quadrature component.
Synthetic interferograms (closed fringe) are
demodulated using the FSD-HSO algorithm.
It should be noted that the
demodulated signal is generally contaminated by high-order harmonics and their amplitude dependencies on the measured phase signal amplitude are also nonlinear.
The
demodulated signal is amplified by an amplifier and digitized by the digitizer circuit.
represents the PRBS sequence with length of 1681; [PRBS.sub.rec](i, p) represents the new sequence with length of 1861 structured by the receiving sequence
demodulated by the OFDM demodulation; p = min(subcarrier [member of] Sliding Window) + 840 determines the starting position of the intercept data; when p = 0, there is no offset.
Vibration spectrums, waveforms and
demodulated data are all crucial when the health of pipeline equipment is being reviewed.
