Power line channel often suffers from impulsive interferences generated by electrical appliances. Therefore, power line communication (PLC) suffers the degradation due to such the impulsive interferences. Middleton’s Class A noise model is frequently utilized for the modeling of such the impulsive noise environment. In this paper, we deal with the Viterbi decoding for convolutional code over ad...

This paper proposes a adaptive regularized noise smoothing algorithm for dense range image using directional Laplacian operatos, which preserves discontinuities and removes Gaussian and impulsive noise, simultaneously. In general, dense range data includes heavy noise such as Gaussian noise and impulsive noise. Although the existing regularized noise smoothing algorithm can easily smooth Gaussi...

This paper addresses the performance evaluation of the multiple input multiple output (MIMO) precoding technique, referred to as max-dmin precoding, over fading channel with impulsive noise in a railway tunnel. Measurements showed that the received signal at the antenna on the moving train roof near the catenary suffers from electromagnetic noise interference (EMI). This implies that the tradit...

This paper presents an experimental study of impulsive noise in urban hospitals and clinics. A receiver was designed to resolve impulsive noise bursts as short as 2 ’s in duration in the 450-MHz band. Extensive measurements were taken at three hospitals and three clinics in three major urban areas across the United States and empirical models are provided for the amplitude, interarrival time, a...

Power line channel often suffers from impulsive interferences generated by electrical appliances. Therefore, power line communication (PLC) makes the degradation due to such the impulsive interferences. Middleton’s Class A noise model is frequently utilized for the modeling of such the impulsive noise environment. In this paper, we deal with turbo decoding for turbo codes over additive white Cl...

It is well known that asynchronous impulsive noise is the main source of distortion that drastically affects the powerline communications (PLC) performance. Recently, more realistic models have been proposed in the literature which better fit the physical properties of real impulsive noise. In this paper, we consider a pulse train model and propose a thorough analysis of the impact of impulsive...

In order to obtain the directions for multiple moving targets under impulsive noise environment, a novel maximum likelihood (ML) algorithm based on quantum cultural geese swarm algorithm (QCGSA) is proposed. The method first sets a special array structure of nonuniform linear array, and then locates the targets in a changing search range, and then designs QCGSA to resolve ML function. Utilizing...

In many wireless systems where multiuser detection techniques may be applied, the ambient channel noise is known through experimental measurements to be decidedly nonGaussian, due largely to impulsive phenomena. The performance of many multiuser detectors can degrade substantially in the presence of such impulsive ambient noise. In this paper, we develop robust multiuser detection techniques fo...

It is well known that some of urban man-made noises can be characterized by a wideband impulsive noise (pure impulsive noise). The presence of this pure impulsive noise may significantly degrade the wireless digital transmission performance. As the data rate becomes higher and the radio bandwidth becomes wider, the performance degradation due to pure impulsive interference may become larger. In...
