Experimental Diagnostics of Impulse Noise
The paper describes methodology of experimental diagnostics examining the influence of small home appliances in operation resulting in the injection of impulse noise into local communication lines. The most important result of practical experiments is a data bank of disturbing impulses that will serve for defining of impulse noise model. Keywords–impulse noise; communication lines; local loop; ...
متن کاملImpulse Noise and Narrowband PLC
We discuss the influence of random-and periodic impulse noise on narrowband (< 500 kHz frequency band) Power Line Communications. We start with random impulse noise and compare the properties of the measured impulse noise with the common theoretical models like Middleton Class-A and Mixed Gaussian. The main difference is the fact that the measured impulse noise is noise with memory for the narr...
متن کاملBlind Channel Equalization in Impulse Noise
This paper presents a robust blind channel equalization technique in impulse noise environments. To suppress impulse noise effectively, the combination of order statistics (OS) and adaptive thresholding is considered. We implement nonlinear adaptation with the OS operation based on the Sato error criterion. The adaptive threshold is calculated using the variance of the input signal. Computer si...
متن کاملImpulse Noise Protection Initiatives in VDSL2 Systems
In recent years, VDSL2 standard has been gaining popularity as a high speed network access technology to deliver triple play services of video, voice and data. These services require strict quality-of-experience (QoE) and quality-of-services (QoS) on DSL systems operating in an impulse noise environment. The DSL systems, in-turn, are affected severely in the presence of impulse noise in the tel...
متن کاملImpulse Noise Suppression in Blind Channel Equalization
In this paper, robust blind channel equalization is addressed in which the combination of order statistics (OS) and thresholding techniques to suppress impulse noise is considered. We implement nonlinear adaptation with the OS operation based on the Sato error criterion. The threshold is calculated using the variance of the input signal. Computer simulations demonstrate that a significant impro...
