Abstract
This disclosure provides systems, methods, and apparatus for wireline communication. Independent control of probing signals transmitted on different power line couplings may be used to characterize power line communication (PLC) signal leakage on a set of digital subscriber line (DSL) lines. For example, PLC packets may be sent on a primary coupling and an alternate coupling, and PLC signal leakage from these couplings may be measured by a device, such as a PLC device or a DSL device, connected to the set of DSL lines. The measurements from each coupling may enable a determination as to which of the couplings (either primary or alternate) is more imbalanced and results in relatively more PLC signal leakage into the set of DSL lines. Accordingly, a transmission power and a precoder may be determined based on the measured PLC signal leakage to mitigate interference on the twisted pair.
