“…In order to express these parameters in terms of the attenuation coefficient, which is often given in nepers, as well as adopt other reference lengths, like in [16], proper scaling must be performed. In this way, one can use the following relation to scale from dB/100 m to Np/100 m: IL(f ) (dB/100 m) = 8.686 × 100 × α(f ), where α(f ) is the cable's frequency dependent attenuation coefficient (given in nepers per meter) and f is the frequency in MHz [20].…”

“…Because of the variability of crosstalk coupling functions, crosstalk is commonly characterized by either stochastic models, which provide distinct realizations of crosstalk channels, or worst-case models. For example, a 1% worst-case FEXT (far-end crosstalk) model predicts that no more than one percent of all FEXT transfer functions in the cable will be more severe than the one derived by the model, as discussed in [19], [31]- [34].…”

G.fast is a new standard from the International Telecommunication Union, which targets 1 Gb/s over short copper loops using frequencies up to 212 MHz. This new technology requires accurate parametric cable models for simulation, design, and performance evaluation tests. Some existing copper cable models were designed for the very high speed digital subscriber line spectra, i.e., frequencies up to 30 MHz, and adopt assumptions that are violated when the frequency range is extended to G.fast frequencies. This paper introduces a simple and causal cable model that is able to accurately characterize copper loops composed by single or multiple segments, in both frequency and time domains. Results using G.fast topologies show that, apart from being accurate, the new model is attractive due to its low computational cost and closed-form expressions for fitting its parameters to measurement data.

“…The noise was assumed to have two components: an additive white Gaussian noise (AWGN) component with a power spectrum density of -114 dBm/Hz and a nearend crosstalk (NEXT) component from 49 pairs. The transfer function for modeling the NEXT was taken as I H N E x T (~)~~ = 10-13f1.5 [12]. Both the TEQ and the target response were assumed to be of order 16.…”

Several design criteria for time-domain equalization in discrete-multitone-based asymmetric digital subscriber line systems are studied. A new criterion that maximizes the signal-to-noise ratio regardless of the profile of bandwidth occupancy is proposed. Based on the new criterion, a procedure for optimizing the bandwidth occupancy is developed. The new criterion is shown to track the change in bandwidth occupancy and thus leads to significant performance gain when combined with bandwidth optimization. Simulations are carried out to quantify the effects of the new criterion and its associated bandwidth optimization on the performance of the system.
