The one‐bit diffusion for distributed beamforming over cell free wireless networks

IET Communications, 2023
This paper presents an investigation into the theoretical performance of diffusion adaptive networks within a distributed beam coordination application in a cell‐free communication network that utilizes coarsely quantized data. This analysis assumed data

A clutter suppression algorithm via subspace‐weighted mixed‐norm minimisation

IET Radar, Sonar & Navigation, 2023
Space‐time adaptive processing (STAP) struggles to effectively suppress clutter in the heterogeneous clutter environment due to the lack of training samples.

Distributed Asymptotic Minimization of Sequences of Convex Functions by a Broadcast Adaptive Subgradient Method [PDF]

, 2011
We propose a non-hierarchical decentralized algorithm for the asymptotic minimization of possibly time-varying convex functions. In our method, each agent in a network has a private, local (possibly time-varying) cost function, and the objective is to ...

Adaptive detection of distributed targets in compound-Gaussian noise without secondary data: A Bayesian approach [PDF]

, 2011
In this paper, we deal with the problem of adaptive detection of distributed targets embedded in colored noise modeled in terms of a compound-Gaussian process and without assuming that a set of secondary data is available.The covariance matrices of the ...

An improved adaptive sidelobe blanker [PDF]

, 2008
We propose a two-stage detector consisting of a subspace detector followed by the whitened adaptive beamformer orthogonal rejection test. The performance analysis shows that it possesses the constant false alarm rate property with respect to the unknown

A novel sparse recovery‐based space‐time adaptive processing algorithm based on gridless sparse Bayesian learning for non‐sidelooking airborne radar

IET Radar, Sonar & Navigation, 2023
Non‐sidelooking airborne radar encounters significant non‐stationary and heterogeneous clutter environments, resulting in a severe shortage of samples.

Adaptive auditory signal processing [PDF]

Psychonomic Science, 1971
An experiment was conducted to investigate adaptive auditory signal processing over series of trials in a standard two-interval temporal forced-choice detection task with stimulus uncertainty. Observer sensitivity was found to be dependent upon both the number of successive repetitions of the test stimulus and the number of correct responses in the ...

IIR array processing based fast adaptive null steering algorithm using shift-invariant subarrays

, 2012
This paper presents and investigates a fast adaptive null steering system employing infinite impulse response (IIR) array processing. The new algorithm is of considerable interest in communications where the desired signal is weak compared with the ...
