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.
