....for DMT transmission system, which also makes good use of the spectrally shaped channel. Since DMT with bit loading makes efficient use of available bandwidth, it has become a good candidate for DSL systems. The characteristics of the wire pair channel have been studied in number of the papers [45], 55] 11] In this thesis, twisted pair cable transfer function is derived from lab measurements using an HP 89410A spectrum analyzer. The transfer function can be modeled as H(d, f) 10 o. e , Rqd (4.1.1) where d is the cable length, art is the maximum attenuation, and RC is the cable ....

....this theoret ical work did not deliver a closed analytic description of impulsive noise. Neither did the empirical measure ments lead to a closed statistical model. Nevertheless, a few important papers and their results should be mentioned shortly. A campaign by British Telecom (see, Cook [10]) was carried out with an equipment based on a filter bank for spectral decomposition. It led to the definition of a socalled symbolic pulse . As the shapes of impulses can differ significantly even on one line, such representative impulses should always be handled with caution. 278 w. Henkel. ....

T. Kc131cr: A Wideband Impulsive Noise. Survey 119 94] No. 6 Especially, the impulse proposed in [10] has nota shape similar to real measured impulses. It was defined as t(t = o, t= o (1) Unfortunately, it also has a pole at time zero and in finite energy. To be sincere, we should say that besides the statistical model described herein, we searched for possibilities to derive representative ....
