Performance Analysis of Hybrid Phase Shift Keying over Generalized Nakagami Fading Channels
Journal of Telecommunications and Information Technology, 2023 In addition to the benefits of hybrid phase shift keying (HPSK) modulation in reducing the peak to average power ratio of the transmitted signal to reduce the zero cross- ings and the 0◦-degree phase transmissions, HPSK enhances the bit error rate (BER)

Phase-shifting algorithms with known and unknown phase shifts: comparison and hybrid
Optics Express, 2022 The phase-shifting interferometry has been intensively studied for more than half a century, and is still actively investigated and improved for more demanding precision measurement requirements. A proper phase-shifting algorithm (PSA) for phase extraction should consider various error sources including (i) the phase-shift errors, (ii) the intensity ...

Phase Shift Strategies in Phase Shifting Time Averaging Interferometry [PDF]
Experimental Techniques, 2021 AbstractClassical time-averaging interferometry technique is widely used for MEMS/MOEMS dynamic behavior investigations. It provides useful information on resonant vibration frequencies and mode shapes in the form of Bessel fringe images. To evaluate the information on objects’ vibration amplitude distribution, one needs to further process Bessel ...
