Multi-carrier digital subscriber line (DSL) systems, such as asymmetric DSL (ADSL) and very high data rate DSL (VDSL), are typically constrained by crosstalk interference. Recent advances in suppression of in-domain far-end crosstalk (self-FEXT) have allowed these systems to achieve very high bidirectional data rates over twisted-pairs of copper wires. However, the performance of these systems is severely degraded in the presence of alien or out-of-domain crosstalk that arises from sources that lie outside the vectored system, usually induced by other twisted-pairs sharing the same binder. In this dissertation, we suggest a practical, non-iterative algorithm for optimum alien crosstalk mitigation. Simulation results and complexity analysis corresponding to a vectored VDSL2 system in presence of alien crosstalk are presented to illustrate the significant performance benefits of the proposed algorithm and its low implementation complexity.
