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.

Claim (Index 19):
A communication system, comprising:\n a transmitter configured to send a plurality of orthogonally polarized signals containing transmit data using faster-than-Nyquist transmission; a receiver comprising a plurality of orthogonally polarized antennas to produce a corresponding plurality of received signals from a composite received version of the polarized signals, the receiver configured to process each of the received signals by applying adaptively controlled amounts of phase rotation; processing with an adaptive feedforward filtering stage; and processing with an adaptive feedback stage to obtain output signals, whereby the output signals are decoded by a data decoding stage to obtain estimates of the transmit data.
