This paper describes a novel efficient algorithm appropriate for adapting filters of long order. The scheme is an exact block processing counterpart of the fast Newton transversal filtering algorithm. The filters required by the algorithm blocks are much smaller than the filter length, and the obtained estimates are mathematically equivalent to those of the sample-by-sample version. This leads to a substantial saving in computational complexity without sacrificing performance as well as not having to resort to long processing delays, which limit the performance of the adaptive system.
