ON TWO-STEP ESTIMATION OF A SPATIAL AUTOREGRESSIVE MODEL WITH AUTOREGRESSIVE DISTURBANCES AND ENDOGENOUS REGRESSORS
Cliff–Ord spatial model Generalized method of moments estimation Limited information estimation
2015/9/24
In this paper, we consider a spatial-autoregressive model with autoregressive disturbances,
where we allow for endogenous regressors in addition to a spatial lag of the dependent variable.
We sugges...
Policies for simultaneous estimation and optimization
Policy uncertainty systems linear systems secondary costs system parameters the gaussian distribution the impulse response system
2015/8/11
Policies for the joint identification and control of uncertain systems are presented. The discussion focuses on the case of a multiple input, single output linear system, with no dynamics and quadrati...
A Space-Time Diffusion Scheme for Peer-to-Peer Least-Squares Estimation
Least-Squares Estimation Diffusion Scheme
2015/6/19
We consider a sensor network where each sensor takes multiple measurements of some unknown parameters, corrupted by independent Gaussian noises. The number of measurements at each node can be nite or ...

On the way to make energy supply independent from fossil resources more and more renewable energy sources have to be explored. Biomass has become an important energy resource during the last years and...
Linear Coherent Estimation with Spatial Collaboration
Distributed Estimation Wireless Sensor Networks LMMSE Estimators Constrained Optimization
2012/7/9
A power constrained sensor network that consists of multiple sensor nodes and a fusion center (FC) is considered, where the goal is to estimate a random parameter of interest. In contrast to the distr...
Atomic norm denoising with applications to line spectral estimation
Atomic norm line spectral estimation Information Theory
2012/4/18
The sub-Nyquist estimation of line spectra is a classical problem in signal processing, but currently popular subspace-based techniques have few guarantees in the presence of noise and rely on a prior...
On the Role of Diversity in Sparsity Estimation
Role of Diversity Sparsity Estimation Information Theory
2011/9/22
Abstract: A major challenge in sparsity pattern estimation is that small modes are difficult to detect in the presence of noise. This problem is alleviated if one can observe samples from multiple rea...
Nearest Neighbour Decoding with Pilot-Assisted Channel Estimation for Fading Multiple-Access Channels
Pilot-Assisted Channel Estimation Fading Multiple-Access Channels Information Theory
2011/8/30
Abstract: We study a noncoherent multiple-input multiple-output (MIMO) fading multiple-access channel (MAC), where the transmitters and the receiver are aware of the statistics of the fading, but not ...
