Title: SYSTEMS AND METHODS FOR INTELLIGENTLY-TUNDED DIGITAL SELF-INTERFERENCE CANCELLATION
Abstract:
A system for digital self-interference cancellation includes a filter that generates a reduced-noise digital residue signal; a channel estimator that generates a current self- interference channel estimate from a digital transmit signal, the reduced-noise digital residue signal, and past self-interference channel estimates; a controller that dynamically sets the digital transform configuration in response to changes in a controller-sampled digital residue signal; and a channel memory that stores the past self-interference channel estimates.
