摘要： Method and arrangement in a telecommunication system for estimating frequency dependent resistance of a transmission line. Insertion loss per length unit of the transmission line at a first frequency is determined. Thereupon a first resistance per length unit based on the determined insertion loss per length unit of the transmission line is calculated. Effective resistance per length unit at a second frequency based on the calculated first resistance is calculated. The calculated effective resistance could be used when estimating the insertion loss for the second frequency and all frequencies of interest.

摘要： A FDR SELT measurement is made in a stop band of a DSL band plan, using a PSD allowed by the PSD mask. Further measurements may also be made in an adjacent pass band and further bands, and the results combined to create a wideband measurement result. When transformed into the time domain (e.g. by inverse Fourier transform to produce the line impulse response) greater resolution in time (and hence greater spatial resolution) is achieved. In order to compensate for AGC calibration errors measurements using different AGC steps may be scaled to fit smoothly to each other. If measurements overlap, measurement results in the region of overlap may be combined in various ways to limit the influence of noise and to create a smooth transition from one measurement to the next.
摘要翻译：使用PSD掩模允许的PSD，在DSL频段计划的停止频段进行FDR SELT测量。还可以在相邻通带和另外的带中进行进一步的测量，并且结果组合以产生宽带测量结果。当变换到时域（例如通过逆傅立叶变换产生线脉冲响应）时，可以获得更高的时间分辨率（因此更大的空间分辨率）。为了补偿AGC校准误差，使用不同AGC步长的测量可以被缩放以相互平滑地相配合。如果测量重叠，重叠区域中的测量结果可以以各种方式组合，以限制噪声的影响并创建从一个测量到下一个测量的平滑过渡。

摘要： Method and arrangement for supporting transmission over a Digital Subscriber Line (xDSL) in the presence of Repetitive Electrical Impulse Noise (REIN). The method involves obtaining a power spectrumof the measured Quiet Line Noise (QLN) for the xDSL,where it is assumed that the QLN comprises a REIN contribution. Aperiodicityis detectedin the QLN power spectrum,and the repetition interval of the periodicityis determined.The power spectrumof the REIN is then estimated, based on the repetition interval of said periodicity. Thus, information associated with the estimated REIN power spectrummay be provided for use by a communication unit, such that mitigation of potentially unfavorable influence/effects of the REIN on said transmission over the xDSL.

摘要： Transmission properties of a telecommunications transmission line may be estimated with improved accuracy by numerical solution for Γ of Z in • jω^C = Γ coth( Γ). At least one curve is adapted to Γ solutions already obtained and a starting point for numerical solution is selected in dependence of the at least one curve and in dependence of an already obtained solution close in frequency. In a first frequency range, starting points for numerical solution may be calculated from a biquadratic equation. In a second frequency range, a line in the complex plane may be adapted to solutions already obtained and new starting points selected in dependence of the line and in dependence of the previous solution. In a third frequency range, two lines in the frequency plane may be adapted to solutions already obtained and new starting points selected in dependence of the lines.
