Jointly optimizing the Virtual Noise mask and the SNR margin for improved service in xDSL systems |

|---|---|---|
In Digital Subscriber Line (DSL) systems, the concept of Virtual Noise was introduced to improve the protection against fluctuating crosstalk and to increase link stability. This paper investigates the joint optimization of the Virtual Noise power spectral density and the initialization SNR margin. A new algorithm is developed for modems to estimate the optimum Virtual Noise power spectral density and the initialization SNR margin from crosstalk measurements. Using this algorithm leads to both a better stability in terms of outage probability and an improvement in the achieved data rates compared to the traditional SNR margin approach. Moreover, it makes the use of the Low Power mode in VDSL2 systems possible. |
