IEEE Transactions on Aerospace and Electronic Systems, 2023 Sparse array is popular in the field of array signal processing. However, in the direction of arrival (DOA) estimation, most research on sparse array assumes Gaussian noise, resulting in a model mismatch in the practical scenarios of impulsive noise.

Parameter estimation of impulsive noise for channel coded communication systems
IET Communications, 2021 In this paper, an impulsive noise estimation algorithm for generating bit log‐likelihood ratios (LLRs) for channel coded systems in impulsive noise environments is proposed. This approach is to design the LLR detector in the maximum‐likelihood (ML) sense,

A Novel Underwater Acoustic Signal Denoising Algorithm for Gaussian/Non-Gaussian Impulsive Noise
IEEE Transactions on Vehicular Technology, 2021 Gaussian/non-Gaussian impulsive noises in underwater acoustic (UWA) channel seriously impact the quality of underwater acoustic communication. The common denoising algorithms are based on Gaussian noise model and are difficult to apply to the coexistence

Impulse Noise Injury Model [PDF]
Military Medicine, 2016 The new Auditory 4.0 model has been developed for the assessment of auditory outcomes, expressed as temporary threshold shift (TTS) and permanent threshold shift (PTS), from exposures to impulse noise for unprotected ears, including the prediction of TTS recovery.Auditory 4.0 is an empirical model, constructed from test data collected from chinchillas ...

Heritage and Sustainable Development, 2023 The highest rate at which information may be reliably sent via a communication link is known as its capacity. In the case of non-Gaussian noise, the capacity of the channel depends on the specific characteristics of the noise, which can cause severe ...

Noises for Impulsive Differential Systems [PDF]
IEEE Access, 2019 Stochastic feedback control has aroused folks’ notice, but little is known on the roles of stochastic noises for the dynamic behavior of impulsive differential systems. In this paper, we mainly study the problem of stochastic stabilization on explosive solutions of nonlinear impulsive differential systems by noises.

Annoyance penalty of impulsive noise – The effect of impulse onset [PDF]
Building and Environment, 2020 Abstract Impulsive sound can be perceived more annoying than a steady-state sound having the same A-weighted equivalent sound pressure level, LAeq. The difference in perceived noise annoyance can be compensated by adding a penalty or an adjustment k to LAeq (rating level).

Fractional Low-Order Moments Based DOA Estimation With Co-Prime Array in Presence of Impulsive Noise
IEEE Access, 2021 Direction of arrival (DOA) estimation with co-prime array is a hot issue in array signal processing. By using co-prime array structure, the degrees of freedom has been greatly improved, which can estimate much more sources than that of the conventional ...

Low rank prior in single patches for non-pointwise impulse noise removal [PDF]
, 2015 This paper introduces a low rank prior in small oriented noise-free image patches: Considering an oriented patch as a matrix, a low-rank matrix approximation is enough to preserve the texture details in the optimally oriented patch.
