Wideband interference mitigation for devices with multiple receivers

Non-transitory physical computer storage comprising computer-executable instructions that, when executed by a computing system, are configured to:

• i.) receive a first signal on a frequency band, wherein the first signal comprises components from a plurality of sub-channels;
• ii.) convert the first signal into a respective plurality of first sub-band frequency components, wherein each sub-band is defined in the frequency domain;
• iii.) determine a respective single-tap spatial filter for each frequency sub-band using one or more corresponding first sub-band components for each respective spatial filter;
• iv.) receive a second signal on said frequency band, wherein the second signal comprises components from the plurality of sub-channels;
• v.) convert the second signal into a respective plurality of second sub-band frequency components;
• and
• vi.) generate a corresponding plurality of filtered sub-band components by applying the respective single-tap spatial filters to the corresponding second sub-band components of the second signal,
• wherein step iii) is performed before any of the steps iv)-vi);
• and
• wherein step iii) is performed without determining that the first signal includes a substantial signal of interest.

A system for suppressing wideband interference, the system comprising:

• an antenna configured to receive wireless signals;
• and
• a processing unit configured to:
• i.) process a first signal on a frequency band received at the antenna, wherein the first signal comprises components from a plurality of sub-channels;
• ii.) convert the first signal into a respective plurality of first sub-band frequency components, wherein each sub-band is defined in the frequency domain;
• iii.) determine, with the assumption that the first signal does not include a substantial signal of interest, a respective single-tap spatial filter for each frequency sub-band using one or more corresponding first sub-band components for each respective spatial filter;
• iv.) process a second signal on said frequency band received at the antenna, wherein the second signal comprises components from the plurality of sub-channels;
• v.) convert the second signal into a respective plurality of second sub-band frequency components;
• and
• vi.) generate a corresponding plurality of filtered sub-band components by applying the respective single-tap spatial filters to the corresponding second sub-band components of the second signal,
• wherein step iii) is performed before any of the steps iv)-vi).
