“…More research is required for efficient crosstalk cancellation on DSL channels at higher frequencies including channel characterization. Iterative processing is another alternative to linear processing with reduced complexity and memory requirements [15]. Dynamic spectrum management improves the DSL performance by optimizing power allocation over the system bandwidth.…”

Interference cancellation is the main driving technology in enhancing the transmission rates over telephone lines above 100 Mbps. Still, crosstalk interference in multi-pair digital subscriber line (DSL) systems at higher frequencies has not been dealt with sufficiently. The upcoming G.(mg)fast DSL system envisions the use of extremely high bandwidth and full-duplex transmissions generating significantly higher crosstalk and selfinterference signals. More powerful interference cancellation techniques are required to enable multi-gigabit per second data rate transmission over copper lines. In this article, we analyze the performance of interference cancellation techniques, with a focus on novel research approaches and design considerations for efficient interference mitigation for multi-gigabit transmission over standard copper lines. We also detail novel approaches for interference cancellation in the upcoming technologies.
