Metameric MIMO-OOK transmission scheme using multiple RGB LEDs [PDF]

, 2018
In this work, we propose a novel visible light communication (VLC) scheme utilizing multiple di erent red green and blue triplets each with a di erent emission spectrum of red, green and blue for mitigating the e ect of interference due to di erent ...

Estimation in Gaussian Noise: Properties of the Minimum Mean-Square Error [PDF]

IEEE Transactions on Information Theory, 2010
Consider the minimum mean-square error (MMSE) of estimating an arbitrary random variable from its observation contaminated by Gaussian noise. The MMSE can be regarded as a function of the signal-to-noise ratio (SNR) as well as a functional of the input ...

Direct normal irradiance predictions using broadband models for Indian stations

Energy Reports, 2020
In this paper three parametric models CPCR2, MLWT2 and REST have been used to compute direct normal irradiance (DNI) for five Indian stations, namely New Delhi, Pune, Jaipur, Kolkata and Mumbai.

DV-Hop Localization Algorithm Based on Minimum Mean Square Error in Internet of Things

International Conference on Identification, Information, and Knowledge in the Internet of Things, 2018
In the practical application of node positioning in the Internet of Things (IOT), the distribution of beacon nodes is generally non-uniform, so there is a certain error in positioning accuracy.

Comparison between the Cramer-Rao and the mini-max approaches in quantum channel estimation

, 2010
In a unified viewpoint in quantum channel estimation, we compare the Cramer-Rao and the mini-max approaches, which gives the Bayesian bound in the group covariant model. For this purpose, we introduce the local asymptotic mini-max bound, whose maximum is

Hessian and concavity of mutual information, differential entropy, and entropy power in linear vector Gaussian channels

, 2009
Within the framework of linear vector Gaussian channels with arbitrary signaling, closed-form expressions for the Jacobian of the minimum mean square error and Fisher information matrices with respect to arbitrary parameters of the system are calculated ...

INTERFERENCE REJECTION OF SIGNALS BY ADAPTIVE MINIMUM MEAN SQUARE ERROR CRITERION OVER RAYLEIGH FADING CHANNELS [PDF]

Journal of Engineering Science and Technology, 2009
Channel time-variation (or fading) is the major source of impairment in digital wireless communications. This occurs due to mobility of the user or of the objects in the propagation environment.

Efficient estimation of population variance of a sensitive variable using a new scrambling response model

Scientific Reports, 2023
This study introduces a pioneering scrambling response model tailored for handling sensitive variables. Subsequently, a generalized estimator for variance estimation, relying on two auxiliary information sources, is developed following this novel model ...
