Gerhard Kramer and former Bell Labs colleague Carl Nuzman will receive a 2012 Thomas Edison patent award from the Research & Development Council of New Jersey for the patent
“Simultaneous Estimation of Multiple Channel Coefficients Using a Common Probing Sequence” (U.S. Patent 8,218,419)
The invention is a pilot-based training scheme that significantly expedites cross-talk estimation for vectored DSL systems using joint estimation over groups of tones. Vectoring DSL systems will allow service providers to provide premium broadband services much sooner and at a much lower cost than would be possible using optical fiber alone.
