On the performance of a hybrid frequency and phase shift keying modulation technique

IEEE Transactions on Communications, 1993
The performance of a hybrid modulation technique derived from binary frequency shift keying is presented. In the hybrid scheme, each frequency is allowed to be phase modulated with any of p discrete, equally spaced phase shifts. The spectral separation between frequencies is chosen to make the carriers orthogonal, thus generating a multidimensional ...

Modulated phase-shifting for 3D scanning

2008 IEEE Conference on Computer Vision and Pattern Recognition, 2008
We present a new 3D scanning method using modulated phase-shifting. Optical scanning of complex objects or scenes with significant global light transport, such as subsurface scattering, interreflections, volumetric scattering, etc. is a difficult task since the direct surface reflection will be mixed with the global illumination.

New phase shift modulator for resonant converters

2015 IEEE International Symposium on Circuits and Systems (ISCAS), 2015
Resonant converters are important in the search for high efficiency energy use and low electromagnetic interference (EMI). In this paper, nonlinarities of the traditional phase shift modulator (PSM) application to resonant converters are addressed. A new modulator topology, suited for resonant converters, is proposed.
