A Simplified Impulse-noise Model for the Xdsl Test Environment
نویسندگان
چکیده
After presenting results of recent impulse-noise measurements in customer premises, a proposal for a simplified statistical model for impulse noise is presented. The new model is intended to replace the deterministic single impulse, widely known as Cook Pulse, especially in the upcoming standards for SDSL and also maybe VDSL. In addition to the statistical model also herein, sample impulses are defined. In contrast to the Cook Pulse, these impulses look like real impulses and are determined from an average power density spectrum and a group-delay average. Such single impulses should allow fast equipment checks but are not very suited for performance tests.

An improved channel model for ADSL and VDSL systems
This paper examines existing channel models used with xDSL systems and identifies a key shortcoming namely, the implicit assumption that all impulse noise originates at the transmitter. Based on extensive data collected from the local loop, a new model is proposed which addresses this problem by combining a digital filter model of the transmission line with a distributed noise source. This bett...

This paper proposes a suitable method for simulating impulses with appropriate amplitude, spectral, and inter-arrival characteristics. The statistics used to develop the parameters of this model are based on statistics derived from observations of impulse noise on the telephone networks of British Telecom (BT) and Deutsche Telekom (DT). This paper initially reviews the former DT approach to imp...

Today many complex models, typically finite element models, have been employed in the analysis of jacket offshore structures. However, these comprehensive models are not readily adopted in engineering practice, especially during the preliminary design stage. As the dynamic analysis of jacket platforms is very complicated, it will be very advantageous to make a simplified computational method to...

Digital image is often degraded by many kinds of noise during the process of acquisition and transmission. To make subsequent processing more convenient, it is necessary to decrease the effect of noise. There are many kinds of noises in image, which mainly include salt and pepper noise and Gaussian noise. This paper focuses on median filters to remove the salt and pepper noise. After summarizin...
