Generalized Error Exponents For Small Sample Universal Hypothesis Testing

open access: yes, 2014
The small sample universal hypothesis testing problem is investigated in this paper, in which the number of samples $n$ is smaller than the number of possible outcomes $m$.

Analysis and Design of Multiple-Antenna Cognitive Radios with Multiple Primary User Signals

open access: yes, 2015
We consider multiple-antenna signal detection of primary user transmission signals by a secondary user receiver in cognitive radio networks. The optimal detector is analyzed for the scenario where the number of primary user signals is no less than the ...

Knowledge-Aided Target Detection for Multistatic Passive Radar

open access: yesIEEE Access, 2019
This paper studies the detection problem for multistatic passive radar. We consider scenarios where prior knowledge about the spectrum and peak-to-average ratio (PAR) of the non-cooperative illuminators of opportunity (IOs) is available.

A Modal-Domain Adaptive Subspace Detector in a Deep-Sea Environment

open access: yesIEEE Access, 2019
In deep-sea environments, the conventional adaptive subspace detector (ASD) is realized in the hydrophone domain by applying the generalized likelihood ratio test (GLRT), in which acoustic signals lie in lower-dimensional modal subspaces. When the number

Rician MIMO Channel- and Jamming-Aware Decision Fusion

open access: yes, 2017
In this manuscript we study channel-aware decision fusion (DF) in a wireless sensor network (WSN) where: (i) the sensors transmit their decisions simultaneously for spectral efficiency purposes and the DF center (DFC) is equipped with multiple antennas; (

Analytical Coherent Detection in High-Resolution Dual-Polarimetric Sea Clutter with Independent Inverse Gamma Textures

open access: yesRemote Sensing
Polarization diversity has been widely used in maritime radars to improve target detection performance. Full utilization of the polarimetric characteristics of sea clutter is the key to designing effective polarimetric detectors.

Adaptive Detection of Structured Signals in Low-Rank Interference

open access: yes, 2019
In this paper, we consider the problem of detecting the presence (or absence) of an unknown but structured signal from the space-time outputs of an array under strong, non-white interference.

Changepoint Detection over Graphs with the Spectral Scan Statistic [PDF]

open access: yes, 2012
We consider the change-point detection problem of deciding, based on noisy measurements, whether an unknown signal over a given graph is constant or is instead piecewise constant over two connected induced subgraphs of relatively low cut size. We analyze

A Novel Decoder for Unknown Diversity Channels Employing Space-Time Codes

open access: yesEURASIP Journal on Advances in Signal Processing, 2002
We suggest new decoding techniques for diversity channels employing space time codes (STC) when the channel coefficients are unknown to both transmitter and receiver.
