Multicarrier basis functions and related issues are overviewed in this article with an emphasis on filtered multitone (FMT) modulation for VDSL. The combination of filtering, small amounts of excess bandwidth, multicarrier channel partitioning and some equalization are shown to allow a good match to spectrum management and performance challenges in VDSL transmission. The FMT basis functions are overviewed in the context of filter banks, with appropriate changes for nonzero excess bandwidth.
