Self-organized complexity and Coherent Infomax from the viewpoint of Jaynes’s probability theory [PDF]

open access: yes, 2012
This paper discusses concepts of self-organized complexity and the theory of Coherent Infomax in the light of Jaynes’s probability theory. Coherent Infomax, shows, in principle, how adaptively self-organized complexity can be preserved and improved by ...

Four-in-one interferometer for coherent and self-coherent detection

open access: yesOptics Express, 2013
A compact micro-optical interferometer is presented that combines two optical 90° hybrids or, alternatively, four delay interferometers into one interferometer structure sharing one tunable delay line. The interferometer can function as a frontend of either a coherent receiver or of a self-coherent receiver by adjusting the waveplates and the delay ...

Self-Homodyne Detection in Optical Communication Systems

open access: yesPhotonics, 2014
We review work on self-homodyne detection (SHD) for optical communication systems. SHD uses a transmitted pilot-tone (PT), originating from the transmitter laser, to exploit phase noise cancellation at a coherent receiver and to enable transmitter ...

Integration of a Self-Coherence Algorithm into DISAT for Forced Oscillation Detection [PDF]

open access: yes, 2015
With the increasing number of phasor measurement units on the power system, behaviors typically not observable on the power system are becoming more apparent. Oscillatory behavior on the power system, notably forced oscillations, are one such behavior.
