SCALE: A Low-Complexity Distributed Protocol for Spectrum Balancing in Multiuser DSL Networks


Dynamic spectrum management of digital subscriber lines (DSLs) has the potential to dramatically increase the capacity of the aging last-mile copper access network. This paper takes an important step toward fulfilling this potential through power spectrum balancing. We derive a novel algorithm called SCALE, that provides a significant performance… (More)
