“…It is seen that the gap between per-tone cancellation and linear cancellation is small for majority of the bins when the misalignment is optimum. Remark: For REIN sources like home appliances the length of the impulse noise burst may be much smaller than the DMT symbol [5]. For these cases, the uncancellable noise energy can be small given that start and/or end portion of the uncancellable signal u(n) (refer (11),(12)) may be zero due to the shorter length of the noise burst.…”

For xDSL systems, alien noise cancellation using an additional common mode sensor at the downstream receiver can be thought of as interference cancellation in a Single Input Dual Output (SIDO) system. The coupling between the common mode and differential mode can be modelled as an LTI system with a long impulse response, resulting in high complexity for cancellation. Frequency domain per-tone cancellation offers a low complexity approach to the problem besides having other advantages like faster training, but suffers from loss in cancellation performance due to approximations in the per-tone model. We analyze this loss and show that it is possible to minimize it by a convenient post-training "delay" adjustment. We also show via measurements that the loss of cancellation performance due to the per-tone model is not very large for real scenarios.

“…We performed measurements of impulse noise that originated from electrical appliances and affected the telephone lines. The principle of measuring the impulse disturbance is described in [5]. The inter-arrival time of the measured impulses has been analysed.…”

“…Figure 3 shows modelling of the new impulse noise with inter-arrival time of impulses with tia = 0.63 ms in the whole interval of 200 ms. The generated impulses in the whole interval have been generated using the method described in [5]; in this case, random phase of impulses has been modelled by the normal Gaussian distribution. The background noise has been modelled as white Gaussian noise with PSD of -140 dBm/Hz.…”

This paper describes methods for theoretical modeling of inter-arrival time of impulse noise and presents a new model based on the application of general mathematical distributions, together with its implementation in MATLAB. It also discusses the suitability of this model for development and testing of digital communication systems intended for deployment on high-voltage power distribution lines.
