Abstract:
1. An apparatus for cancelling interference imposed on a received communications signal, comprising: a first and a second adaptive filter configured to adjust a first digital sequence from among a plurality of digital sequences according to a first set of filtering coefficients to provide a first adjusted digital sequence and to adjust a second digital sequence from among the plurality of digital sequences according to a second set of filtering coefficients to provide a second adjusted digital sequence, respectively; a first and a second combination module, the first combination module being configured to combine a third digital sequence from among the plurality of digital sequences and the first adjusted digital sequence to provide a first corrected digital sequence from among a plurality of corrected digital sequences, the second combination module being configured to combine the first corrected digital sequence and the second adjusted digital sequence to provide a second corrected digital sequence from among the plurality of corrected digital sequences; and a first switching module configured to cause the first adaptive filter to update the first set of filtering coefficients based upon the first corrected digital sequence in a first configuration or based upon the second corrected digital sequence in a second configuration.
