Efficient Deep Wavelet Gaussian Markov Dempster–Shafer Network-Based Spectrum Sensing at Very Low SNR in Cognitive Radio Networks [PDF]
Cognitive radio networks (CRNs) rely heavily on spectral sensing to detect primary user (PU) activity, yet detection at low signal-to-noise ratios (SNRs) remains a major challenge.

Adaptive Signal Detection with Finite Memory [PDF]
In the Bayesian approach to signal-detection theory, infinite soft or changeable memory is tacitly assumed. Since an infinite memory is physically unrealizable, this study is concerned with formulating and optimizing a finite memory applicable to a large class of signal-detection problems. An optimum finite memory design is presented, assuming a priori

Detecting multiple replicating signals using adaptive filtering procedures
Replicability is a fundamental quality of scientific discoveries: we are interested in those signals that are detectable in different laboratories, study populations, across time etc. Unlike meta-analysis which accounts for experimental variability but does not guarantee replicability, testing a partial conjunction (PC) null aims specifically to ...

A Tunable Adaptive Detector for Mismatched Signal
The adaptive detection problem for mismatched useful signal is considered. A novel parametric adaptive detector is proposed, and the adaptive matched filter and double normalized adaptive matched filter are the special cases of the tunable detector.

Generalised RAO test for polarimetric target detection
Here, a generalised Rao test method is presented for polarimetric multichannel adaptive signal detection. By introducing several tunable parameters into the Rao test detection statistics, the proposed polarimetric detector is quite general with the ...
