Combination of per Tone Equalization and Windowing Indmt -

High speed Digital Subscriber Line (DSL) systems transmit signals that overlap in spectrum with the bands used for radio communications. AM broadcast stations and radio amateur transmitters result into electromagnetic interference impairing the DSL-receiver. For Discrete Multitone (DMT) systems, windowing, in combination with Radio Frequency Interference (RFI) cancellation has been proposed to make DSL-transceivers robust to radio ingress. This paper shows how win-dowing has an equivalent implementation by means of per tone equalizers. Attractive to the per tone equalizer structure is that per carrier, the equalizer can be optimized to reduce susceptibility to RFI.
