  • Systems and methods for intelligently-tuned digital self-interference cancellation
    Patent number: 11121737
    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; a predictor that modifies output of the channel estimator to compensate for a first time delay incurred in tuning the system for digital self-interference cancellation; and a channel memory that stores the past self-interference channel estimates.
    Type: Grant
    Filed: September 17, 2020
    Date of Patent: September 14, 2021
    Assignee: Kumu Networks, Inc.
    Inventors: Rajendra Tushar Moorti, Kumar Viswanatha
