Abstract

The next generation of digital subscriber line (DSL) standard will require the development of enabling technologies to exploit currently unused higher frequencies in the very and ultra high frequency bands over a shorter copper drop. At these higher frequencies, the indirect channels produced by the electromagnetic coupling (EMC) between pairs in a binder cable may be as strong as, or stronger than, the direct channels. In this work, we exploit the isomorphism between this wireline environment and the well-studied multipath wireless models to propose a full duplex wired MIMO system for the legacy copper connection in a point-to-point backhaul network. The proposed system achieves self-interference suppression and exploitation of the diversity offered by the EMC channels through a joint interoperable pre-coding scheme consisting of null space projection (NSP) and maximum ratio combining (MRC). Channel measurements for a 10 pair binder cable are used to evaluate the performance of the proposed system.
