Experimental Study and Application of Response Mask Invariant Characteristic for Generalized Visible Light Communication Channel

open access: yesIEEE Photonics Journal, 2018
In this paper, we describe a generalized visible light communication (VLC) channel, which consists of the frequency responses of the light emitting diode (LED), the wireless optical channel, and the photo detector (PD).

Meandering evolution and width variation, a physics-statistical based modeling approach [PDF]

open access: yes, 2018
Many models have been proposed to simulate and understand the long-term evolution of meandering rivers. These models analyze the hydraulics of the in-channel flow and the river bank movement (erosion \u2013 accretion) process in different ways, but some ...

Necessary and sufficient conditions for local creation of quantum discord

open access: yes, 2012
We show that a local channel cannot create quantum discord (QD) for zero QD states of size $d\geq3$ if and only if either it is a completely decohering channel or it is a nontrivial isotropic channel.
