Abstract: A system for wired analog self-interference cancellation includes a coarse delayer that delays a sampled RF transmit signal by a first delay amount; a frequency downconverter that downconverts the sampled RF transmit signal to IF; a first canceller tap group comprising a first per-tap-group delayer, a first sampling coupler, a first per-tap delayer, and first and second analog vector modulators that generates an IF self-interference cancellation signal; a frequency upconverter that upconverts the IF self-interference cancellation signal to RF; and a receive coupler that combines the RF self-interference cancellation signal with the RF receive signal, reducing self-interference.

Abstract: A method for self-interference canceller tuning for a near band radio includes receiving, in a first frequency band, an RF transmit signal of the near band radio; receiving, in a second frequency band, an RF receive signal of the near band radio; generating a self-interference cancellation signal from the RF transmit signal based on a set of configuration parameters; combining the self-interference cancellation signal with the RF receive signal to create a composite receive signal; and adapting the set of configuration parameters based on the compo-site receive signal.

Abstract: A system for interference cancellation, preferably including a plurality of analog taps. Each analog tap preferably includes one or more scalers and/or phase shifters, and can optionally include one or more delays. The system for interference cancellation can optionally be integrated with and/or otherwise associated with a MIMO communication system. A method for interference cancellation, preferably including: determining operation parameters and operating based on the determined parameters. The method is preferably performed using the system for interference cancellation (e.g., and/or an associated MIMO communication system), but can additionally or alternatively be performed using any other suitable system.
