Theoretically the proposed demodulation scheme is not influenced by the zeros of the Bessel functions, and can keep a good performance in a wide range of modulation depth. It is compared with ...

Abstract: Aiming at realizing high-efficiency distributed strain sensing through optical frequency domain reflectometry (OFDR), this paper introduces a fast demodulation algorithm to determine ...

Advanced, patent pending, signal processing in the MPRE provides robust and reliable QPSK demodulation in high Doppler and mobile multipath environments. Mobile multipath radio environments that are ...

MATLAB Imitation Modeling for the BER of the Satellite Communication System using QPSK and OFDM Modulation with LS Channel Estimation based on Pilot Signals in the Transionospheric Communication ...

QAM signal constellations are supported, including QAM16, QAM64 and QAM256. QPSK, and BPSK are also supported. The operation of the demodulator is automated by a master finite state machine. The LDPC ...
