Signal processing played an important role in improving the quality of communications over copper cables in earlier DSL technologies. Even more powerful signal processing techniques are required to enable a gigabit per second data rate in the upcoming G.fast standard. This new standard is different from its predecessors in many respects. In particular,(More)
Signal processing played an important role in improving the quality of communications over copper cables in earlier digital subscriber line (DSL) technologies. Even more powerful signal processing techniques are required to enable a gigabit per second data rate in the upcoming fast access to subscriber terminals (G.fast.) standard. This new standard is(More)
In this article, we propose a vectored system by using both common mode (CM) and differential mode (DM) signals in upstream VDSL. We first develop a multi-input multi-output (MIMO) CM channel by using the single-pair CM and MIMO DM channels proposed recently, and study the characteristics of the resultant CM-DM channel matrix. We then propose a low(More)
