Abstract :
Cooperation of transceivers on signal level at the remote terminal-often referred to as vectoring-is an effective approach to mitigate crosstalk in wireline transmission systems. While the gain in bitrate compared to crosstalk-limited transmission is substantial, the initialization of a vectoring system requires time and care to ensure system stability. In this contribution, a fast initialization scheme for vectored wireline systems based on spectral protection is analyzed. Two scenarios are considered, where in the first one no prior channel information is available, and in the second one erroneous prior knowledge of channel coefficients is utilized. Measurements on a commercial VDSL2 vectoring platform and throughput simulations demonstrate the potential of the fast initialization scheme.
