  • Spatial interference cancellation for simultaneous wireless and information power transfer
    Patent number: 10804988
    Abstract: A discrete-time delay (TD) technique in a baseband receiver array is disclosed for canceling wide modulated bandwidth spatial interference and reducing the Analog-to-Digital Conversion (ADC) dynamic range requirements. In particular, the discrete-time delay (TD) technique first aligns the interference using non-uniform sampled phases followed by uniform cancellation using a cancellation matrix, such as, for example, a Truncated Hadamard Transform implemented with antipodal binary coefficients.
    Type: Grant
    Filed: September 9, 2019
    Date of Patent: October 13, 2020
    Assignees: Washington State University, The University of British Columbia
