In this paper a novel class of filters designed for the removal of impulsive noise in color images is presented. The proposed filter family is based on the kernel function which regulates the noise suppression properties of the proposed filtering scheme. The comparison of the new filtering method with standard techniques used for impulsive noise removal indicates superior noise removal capabili...

Robust single-user detection is employed in a DS/CDMA system in which the noise proc(ess cent ains impulsive components. The breakdown point is computed for a mixture noise model. Noise rather than interference is shown to be the primary obstacle in achieving good performance when the signal power is low. The bit error probability expressions are also derived under a Gaussian mixture, DS/CDMA e...

Turbo codes occupy a special place in the field of wireless communications for their outstanding performances in correcting errors that appear on transmission channels. This paper analyzes the influence of trellis termination methods on turbo codes performances, over a channel affected by impulsive noise and Binary Phase-Shift Keying modulation. The statistical model used for the impulsive nois...

Digital images are mostly corrupted by mixed noise from several sources. It is a challenging problem to remove mixed noise in color images. Generally, some image denoising filters can reduce either additive or impulse noise, but it fails to remove both impulsive noise and additive noise. This paper presents modified bilateral filtering method, which can simultaneously remove both impulsive and ...

Currently, narrowband Power line communication (PLC) is considered as an attractive communication system in smart grid environments for applications such as advanced metering infrastructure (AMI). In this paper, we will present a comprehensive comparison and analysis in time and frequency domain of noise measured in China and Italy. In addition, impulsive noise in these two countries are mainly...

Smart grid can be a solution for reducing greenhouse gas (GHG) emissions. To perform its task, smart grid needs a communication link to communicate between nodes or devices. Using power-line communications (PLC) is beneficial as the power-lines infrastructure has been available. However, in PLC the transmitted signal undergoes multipath channels and impulsive noise corruption. Meanwhile, orthog...

OBJECTIVE The preference for sooner smaller over larger later rewards is a prominent manifestation of impulsivity in ADHD. According to the State Regulation Deficit (SRD) model, this impulsive choice is the result of impaired regulation of arousal level and can be alleviated by adding environmental stimulation to increase levels of arousal. METHOD To test this prediction, we studied the effec...

This research studied the effect of additive and multiplicative noise in images, and their solution. Salt n pepper, and Gaussian noise is considered as a additive noise, while impulsive noise is considered as a multiplicative noise. For additive noise, this paper presents the outcome of Wiener filter, and Pseudo inverse filter, while for impulsive noise, we studied wavelet denoising. A hybrid f...

This paper presents a subband adaptive filter (SAF) for a system identification where an impulse response is sparse and disturbed with an impulsive noise. Benefiting from the uses of l1-norm optimization and l0-norm penalty of the weight vector in the cost function, the proposed l0-norm sign SAF (l0-SSAF) achieves both robustness against impulsive noise and much improved convergence behavior th...

For active noise control problems, when noise sources are contaminated by impulsive noise, the classic FxLMS converges slowly or even diverges. In order to effectively control such impulsive noise sources, by minimizing the L1-norm of an error vector, a modified filteredx affine projection sign algorithm (MFxAPSA) has been proposed. An exact efficient implementation can greatly reduce its numbe...
