Location Estimation and Detection in Wireless Sensor Networks in the Presence of Fading
Xue Zhang, Cihan Tepedelenlioglu, Mahesh K. Banavar +2
In this paper, localization using narrowband communication signals are considered in the presence of fading channels with time of arrival measurements. When narrowband signals are…
Direct estimation of density functionals using a polynomial basis
Alan Wisler, Visar Berisha, Andreas Spanias +1
A number of fundamental quantities in statistical signal processing and information theory can be expressed as integral functions of two probability density functions. Such quantit…
Empirically Estimable Classification Bounds Based on a New Divergence Measure
Visar Berisha, Alan Wisler, Alfred O. Hero +1
Information divergence functions play a critical role in statistics and information theory. In this paper we show that a non-parametric f-divergence measure can be used to provide…
Distributed SNR Estimation using Constant Modulus Signaling over Gaussian Multiple-Access Channels
Mahesh K. Banavar, Cihan Tepedelenlioglu, Andreas Spanias
A sensor network is used for distributed joint mean and variance estimation, in a single time snapshot. Sensors observe a signal embedded in noise, which are phase modulated using…
On Inequalities Relating the Characteristic Function and Fisher Information
Cihan Tepedelenlioglu, Mahesh K. Banavar, Andreas Spanias
A relationship between the Fisher information and the characteristic function is established with the help of two inequalities. A necessary and sufficient condition for equality is…
Distributed Detection over Fading MACs with Multiple Antennas at the Fusion Center
Mahesh K. Banavar, Anthony D. Smith, Cihan Tepedelenlioglu +1
A distributed detection problem over fading Gaussian multiple-access channels is considered. Sensors observe a phenomenon and transmit their observations to a fusion center using t…
