ADSL FEXT Cancellation with FIR Filters and a Comparative Study

In this paper we investigate a new technique in FEXT cancellation along with the comparison with other techniques in this area of research. In our algorithm, FIR filters are derived from channel and crosstalk transfer functions, which are the key part of FEXT canceling process. Its comparison with Vectored-DMT and Adaptive Multi-User Power Control shows its effectiveness in removing FEXT without the need for coordination and synchronization between users.
