Abstract
An interference mitigation apparatus, comprising: an adaptive feedforward filtering stage and an adaptive feedback filtering stage configured to produce a plurality of output signals from a plurality of frequency downconverted signals, the output signals for being provided to a data decoding stage; a plurality of phase rotators configured to apply phase rotation to the frequency downconverted signals prior to processing by the adaptive feedforward filtering stage and the adaptive feedback filtering stage; and an adaptive controller configured for varying an amount of the phase rotation applied by the phase rotators to the frequency downconverted signals based at least in part on symbol decisions made on the output signals. There may be second phase rotators configured to apply phase rotation after the adaptive feedforward filtering stage so as to produce the output signals for forwarding to the data decoding stage.
