1. An interference canceling apparatus for canceling, from a target signal generated from a target source, an interference signal generated by an interference source, said apparatus comprising:

  • a main input for inputting said target signal;

    a reference input for inputting said interference signal;

    a beam splitter for beam-splitting said target signal into a plurality of band-limited target signals and beam-splitting said interference signal into band-limited interference signals, wherein the amount and frequency of band-limited target signals equal the amount and frequency of band-limited interference signals, whereby for each band-limited target signal there is a corresponding band-limited interference signal;

    an adaptive filter for adaptively filtering, each band-limited interference signal from each corresponding band-limited target signal.
