The present disclosure generally pertains to systems and methods for cancelling crosstalk in satellite access devices, such as DSLAMs. In one exemplary embodiment, a satellite DSLAM is configured to employ a vectored DSL modulation format, such as vectored VDSL, on both a customer premises (CP) side of the DSLAM and a network side of the DSLAM. For at least one tone communicated by the DSLAM, the DSLAM is configured to maintain a set of coefficients indicative of crosstalk contributions from interferers on both sides of the DSLAM. Based on such coefficients, the DSLAM is configured to cancel crosstalk that couples from one side of the DSLAM to the other. |
